1.6 Flame Ionization Detector Operation
DataFID/MicroFID II uses a flame ionization detector to measure total volatileorganic compounds (TVOCs) in air at ppm or ppb levels. Permanent air gases(argon, carbon dioxide, nitrogen, oxygen, water vapor, etc.) are not ionized by theflame and, therefore, are not measured.
When the DataFID/MicroFID II hydrogen flame is ignited, the internal pump draws
in air through the inlet. This sample provides the oxygen necessary for combustion.

Repeller Electrode(Jet +75 V)
Flame Arrestor
Sample In

When the proper hydrogen-to-air ratio is present in the combustion chamber, aglow plug will automatically ignite the flame. Flame status, whether lit or
extinguished, is monitored by a thermocouple.
Volatile organic compounds (VOCs) are ionized when the sample passes throughthe flame. These ionized molecules are subjected to a continuous electric field
between the repeller electrode at the jet and the collector electrode.
The ions moving in this electric field generate a current that is proportional to theconcentration of the ionized molecules in the combustion chamber. An
electrometer circuit converts this current to a voltage which is sent to themicroprocessor.
After the sample passes through the flame it is vented through a flame arrestor,
also known as the exhaust frit. The flame arrestor prevents the flame from igniting
any flammable gases present in the sampling location.

DataFID/MicroFID II Operating Manual

WARNING
The flame arrestor must be in place to ensure intrinsic
safety during DataFID/MicroFID II operation. Removing theflame arrestor when operating the DataFID/MicroFID II
voids the intrinsic safety rating of the instrument.

1.6.1 Detector Response
DataFID/MicroFID II detects volatile organic compounds. It does not detect
inorganic compounds. The combustion efficiency of a compound determines
sensitivity, which is highly dependent on chemical structure and bonding
characteristics.
Simple saturated hydrocarbons (methane, ethane) possess high combustion
efficiencies and are among the compounds that produce the highest
DataFID/MicroFID II response. Organic fuels (acetylene, refined petroleum
products), also burn easily and are well-detected.
The presence of substituted functional groups (amino, hydroxyl, halogens) on asimple hydrocarbon reduces combustion efficiency. DataFID/MicroFID II detects
methane more easily than the compounds methanol and chloromethane. If
substituted functional groups are present, then a greater number of carbon atoms
can offset this loss of sensitivity.
For example, DataFID/MicroFID II is more sensitive to n-butanol than to methanol.
See section 3.8.9, Compound Selection and Response Factors, on page 3-33 formore information on response factors.
NOTE: The Technical Note “FID Response Factors” Technical Note provides
DataFID/MicroFID II response factors for a variety of VOCs and isavailable for download from www.inficon.com.

1.7.2 Hydrogen Gas
The DataFID/MicroFID II detector uses a hydrogen flame to ionize samples andproduce concentration readings. The quality and purity of the hydrogen gas isimportant to the accuracy of the detector.

DANGER
Hydrogen gas is a fire and explosion hazard when
exposed to heat or flame. Read the hydrogen material
safety data sheet (MSDS), provided by the gas supplier,before handling hydrogen.
The lower explosive limit (LEL) of hydrogen is 4%.
The LEL is the minimum concentration of gas or vapor
in air that will ignite in the presence of a heator ignition source.
The DataFID/MicroFID II hydrogen fuel cylinder must be filled using the Hydrogen
Filling Station (PN 951-601-P1, A1201222, or 951-602-P1). (See section 2.3,
Filling the Hydrogen Fuel Cylinder, on page 2-16 for more information.)
When filling the hydrogen fuel cylinder:Use only Ultra-High Purity hydrogen (99.999% purity) to fill the hydrogen fuelcylinder, also referred to as Grade 5.

The hydrogen supply cylinder pressure must not exceed 3,000 psig (20,684kPa), which is the maximum pressure rating of the Hydrogen Filling Station.

1.7.3 Calibration Gas
DataFID/MicroFID II can be calibrated using zero air and 500 ppm methane. A flow
match regulator (PN MX704210) is available for calibration gases in pressurized
cylinders. The instrument can be calibrated either by sampling directly from the gas
cylinder or by using a sample bag. (See section 3.9, DataFID/MicroFID II
Calibration, on page 3-37 for more detail.)1 – 11

DataFID/MicroFID II Operating Manual

1.7.4 Oxygen Concentration Limits
The sample, drawn in by the pump, supplies the oxygen required to ignite andmaintain the hydrogen flame.
A minimum of 17% oxygen is required to ignite the hydrogen flameA minimum of 10% oxygen is required to maintain the hydrogen flameAn oxygen deficiency will reduce or extinguish the flame, which may alter
the displayed reading

If DataFID/MicroFID II is used in a highly contaminated area where the oxygen
content may be below 10%, monitor for indications of reduced flame intensity,
such as lowered detection limits or a flame out fault

NOTE: DataFID/MicroFID II will not ignite nor maintain the hydrogen flame ataltitudes greater than 2134 m (7000 ft.) due to the decrease in partialpressure of oxygen.

1.7.5 Flammable Gases
High concentrations of flammable gases can act as an additional fuel source.
If the flame intensity increases beyond the confines of the combustion chamber,the hydrogen gas supply will suspend and the flame will extinguish.
When sampling enclosed or confined spaces, vapors and gases may be unable toescape. A high concentration of sample gas can lead to oxygen deficiency and may
extinguish the flame. Monitor for indications of increased flame intensity such as
erratic readings or sudden high concentrations, followed by a flame out fault.

2.3 Filling the Hydrogen Fuel Cylinder
Two types of metal hydride hydrogen fuel cylinders may be used with
DataFID/MicroFID II. (See Figure 2-27.) A 70 L hydrogen fuel cylinder can be used
but is no longer available for purchase. A 10 L Hydrostik hydrogen fuel cylinder has
replaced the 70 L cylinder. Both cylinder types store hydrogen through anabsorption process onto the metal hydride contained in the cylinder. Hydrogen isreleased from the cylinder at a pressure of 80 psi. This low pressure releaseprovides a safe hydrogen source for field use.
NOTE: The 70 L hydrogen fuel cylinder can only be shipped as hazardous
materials via ground transportation, provided it undergoes an ultrasonicrequalification within five (5) years from the date stamped on the cylinder.
NOTE: The 10 L Hydrostik hydrogen fuel cylinder may be shipped as hazardous
goods via air or ground. Up to two Hydrostiks can be transported incarry-on luggage. The expiration of Hydrostik is stamped on the bottom of
the cylinder. It has a ten (10) year shelf life.

DataFID/MicroFID II Operating Manual

When full, a 10 L Hydrostik hydrogen fuel cylinder can provide 10 hours ofcontinuous operation on a DataFID/MicroFID II. A full Hydrostik (without theadapter attached) can be stored up to a month.
NOTE: The Hydrostik can be filled up to 100 times.
A 70 L hydrogen fuel cylinder can provide 70 hours of continuous operation on a
DataFID/MicroFID II.
A hydrogen filling station (PN 951-601-P1, A1201222, or 951-602-P1) is required
to fill the hydrogen fuel cylinders. The hydrogen filling station is equipped witheither a CGA 350 fitting (see Figure 2-28, PN 951-601-P1 and A1201222), or aninternational version without a fitting (see Figure 2-29, PN 951-602-P1) for use withhigh pressure ultra-high purity (UHP) or 99.999% pure grade hydrogen.
NOTE: The user must supply the appropriate hydrogen supply cylinder regional
fitting for the international hydrogen filling station.
Hydrogen filling station (PN 951-601-P1) and the international hydrogen filling
station (PN 951-602-P1) contain a three-way output valve, a hydrogen fuel cylinder
quick connect, and a pressure-reducing regulator with a pressure gauge installed.
The pressure gauge on the regulator provides the pressure reading in thehydrogen supply cylinder.
Hydrogen filling station (PN A1201222) consists of an adapter fitting with aleft-handed thread for cylinder attachment, a three-way output valve, a hydrogenfuel cylinder quick connect, and a pressure-reducing regulator.

CAUTION
Ensure that any fitting attached to the hydrogen filling
station has not been used with any H2S, SO2, Cl2, or CO
supply cylinders prior to using with Ultra High Purity(UHP) hydrogen supply cylinders. These compounds cancontaminate the metal hydride within the hydrogen fuelcylinder and reduce the hydrogen storage ability.

CAUTION
Lower purity grades of hydrogen will contaminate thehydrogen fuel cylinder with impurities and decrease its
longevity. Use only ultra-high purity hydrogen (99.999%)
to fill the hydrogen fuel cylinder.

2.7.3 Data Communication
DataFID/MicroFID II communicates via Bluetooth with an external computer for
uploading information to DataFID/MicroFID II and for downloading measurement
data. Bluetooth also communicates with handheld computers used for LDAR
monitoring.
See Chapter 4, Wireless Communication, for more information regarding Bluetooth
set up and operation.

2.7.4 Method 21 Operation
Method 21 is a United States Environmental Protection Agency (US EPA) sampling
protocol for the determination of volatile organic compound (VOC) leaks in processequipment, Leak Detection and Repair (LDAR). It also has been adopted by thelandfill industry for surface methane emissions monitoring.
The specifications outlined in the Method 21 documentation must be followed whenmonitoring regulated sites.
DataFID/MicroFID II can be pre-programmed to identify and monitor various
locations as required by US EPA Method 21. See Set DataFID/MicroFID II to
Interval mode: on page 3-11 and section 3.7.1, Upload METHOD 21 Route Entryfrom a Computer (DataFID only), on page 3-16.
Since each location may contain different compounds and concentration ranges,
the response factor of the compound(s) being monitored can be stored prior to
sampling. (See section 3.8.9, Compound Selection and Response Factors, on
page 3-33.)

2.7.5 Response Factors
Response factors for identified compounds are available for DataFID/MicroFID II
and can be downloaded from the INFICON website. To enter these response
factors prior to sampling, see section 3.8.9, Compound Selection and Response
Factors, on page 3-33.
NOTE: DataFID/MicroFID II will ionize and respond to all organic compounds.
Since total VOCs will be detected, a response factor representing thedominant VOC in the sample gas should be used.

DataFID/MicroFID II takes one sample measurement every second. In Intervalmode, an average of the sample measurements within the predefined period isrecorded.
In Location or Method 21 (DataFID only) mode, a log file is created that contains
the date, time, status, TVOC reading and a user-defined character string which cancontain up to twenty characters.
NOTE: DataFID/MicroFID II does not delete the data log when changing from one
user mode to another. For example, if the mode is switched from Interval
to Location, the Interval mode log entries are not deleted.

CAUTION
When DataFID/MicroFID II memory is full, previous
entries are overwritten starting with entry 1.

3.6.1 Interval Mode – Data Logging
Interval mode readings are logged at a user-predefined interval between 1 to 999
seconds. DataFID/MicroFID II accumulates all readings in the interval selected anddetermines an average reading. DataFID/MicroFID II stores the average reading,the highest priority instrument status, and the current time and date. (See Figure3-23.)

3.8.9 Compound Selection and Response Factors
It is often impractical to carry a range of different standards into the field. Specialty
gas measurements can be obtained by calibrating DataFID/MicroFID II with therecommended span gas and entering the appropriate response factor for the
specific sample gas. The response factor is based on the ratio of the response of
the specific compound to the response of the span gas.
NOTE: Response factors for identified compounds are available for
DataFID/MicroFID II and can be downloaded from the INFICON website.
To enter these response factors prior to sampling, see section 3.8.9,
Compound Selection and Response Factors, on page 3-33.
The response of a flame ionization detector to a compound is dependent on its
ionization potential. In situations when only a single specific compound exists,
calibrate DataFID/MicroFID II using methane, hexane, or propane. See Section
3.9, DataFID/MicroFID II Calibration, on page 3-37, for calibration instructions.
DataFID/MicroFID II has seven memory slots that are used to store information
regarding individual gases. By default, these memory slots are set to measuremethane with the Compound Name as a blank, Response Factor set to 1.0,
Alarm Level set to 1000.0, and a Formula Weight of 16.0.
The desired compound can be selected for use during measurement. When thedesired compound is displayed, press select to choose the compound. The
individual parameters can be edited to allow for custom compound detection.
(See Figure 3-47.)
NOTE: DataFID/MicroFID II measures TVOCs and will respond to all ionizable
compounds present in a sample. When programming a Response Factor,
use one for a compound that is closest to the expected sample to measure.

3.9 DataFID/MicroFID II Calibration
3.9.1 Calibration Technical Description
Calibration is required to correlate detector signal response and the span gas
concentration, such that DataFID/MicroFID II can display the VOC concentration
measurement in ppm or ppb units. Calibration can also compensate fortemperature and climate changes as well as output changes due to inlet filter
restrictions, combustion chamber cleanliness, sample pump wear, and otherfactors.
During calibration, DataFID/MicroFID II is first exposed to zero air. The signal level
generated is used to set the zero point for the DataFID/MicroFID II. This reading isstored as part of the calibration.
NOTE: Since DataFID/MicroFID II is very sensitive, ambient air is usually
unsuitable for calibration. Ultra zero air should be used for calibration. If
ultra zero air is unavailable, use a charcoal filter (PN MX396022) to filterhydrocarbons from the ambient air.
Next, span (calibration) gas is connected and measured by DataFID/MicroFID II.
The zero point signal is subtracted from the span gas measurement signal, and theresult is divided by the gas concentration, entered by the user. The resulting
sensitivity is stored in the selected memory slot with the zero signal and the alarmlevel. This number is then multiplied by the span gas response factor anddisplayed.
DataFID/MicroFID II readings are always relative to the span gas. A reading of 10
ppm indicates all ionizable compounds that are present have generated an ion
current proportional to 10 ppm of the selected span gas. Almost all combustibleorganic compounds can be detected by DataFID/MicroFID II. However,
DataFID/MicroFID II cannot distinguish between the selected span gas and otherionizable compounds.

3 – 37

DataFID/MicroFID II Operating Manual

A mix of methane with an air balance is recommended as the span gas. If desired,a mix of hexane with an air balance, or propane with an air balance, can also be
used. Use the DataFID Setup or MicroFID II Setup Menu then Selecting
Calibration Gas to enter the span gas being used. The concentration of the spangas will depend on the application.
NOTE: When ordering span gas, ensure it is diluted in ultra zero air.
NOTE: Method 21 protocol requires that commercial cylinders of span gas beanalyzed and certified to be within +/- 2% accuracy and that a shelf life
must be specified on the cylinder. At the end of the shelf life, the cylinder
must be replaced or re-analyzed.

CAUTION
Allow DataFID/MicroFID II to warm-up (equilibrate) for atleast thirty minutes before calibrating to ensure an
accurate calibration.

3.9.2 Preparing for Calibration
3.9.2.1 Calibration Techniques
There are two calibration techniques:

Direct connection of the calibration gas to DataFID/MicroFID II through aflow-match regulator. This is the preferred technique and provides the best
accuracy.
(See section 3.9.2.1.1.)



Use a Tedlar bag filled with calibration gas and connect the bag to
DataFID/MicroFID II. This technique is less preferred due to potential error
introduced if the bag is compressed or squeezed. (See section 3.9.2.1.2.)

3.9.2.1.1 Using a Flow-Match Regulator

WARNING
Operate in a well-ventilated area. Observe proper
handling procedures for pressurized, flammable gases.

1 Ensure DataFID/MicroFID II and the span gas cylinder is in the upright position.
2 Connect the regulator to the span gas cylinder.
3 When using the portable cylinder containing 500 ppm methane span gas(PN MX396028), connect the regulator (PN MX704210) directly to the cylinder.
(See Figure 3-53.) Other span gas compounds and concentrations can be usedas necessary.

DataFID/MicroFID II Operating Manual

4 When the regulator is connected properly and opened, cylinder pressure canbe read from the regulator gauge.

5 Connect the adapter tubing to the regulator, then connect the other end of thetubing to the DataFID/MicroFID II inlet.

6 Open the regulator by turning the valve counter-clockwise, until the gas flow is
audible.

DataFID/MicroFID II Operating Manual

5.2 Maintenance of the Flame Ionization Detector
The flame ionization detector in DataFID/MicroFID II is not field replaceable. If a
detector failure or malfunction is suspected, please contact INFICON Service.

5.3 Replacing Inlet Filter
A sample inlet Fluoropore filter (PN MX396015) is installed under the inlet filter
housing to remove dust particulates and water droplets from the gas sample toprevent detector contamination. The inlet flow rate may decrease as dust andwater droplets accumulate on the filter, resulting in loss of sensitivity.

CAUTION
Aspirating liquids into DataFID/MicroFID II will cause
damage to the sample pathway.
Replace the inlet filter on a daily basis, or more frequently if DataFID/MicroFID II isused in a dusty or wet environment. The filter must be replaced if DataFID/
MicroFID II has been exposed to liquids or water. The pump will sound laboredwhen the filter requires replacement.

WARNING
Do not replace the inlet filter in a potentially hazardous
environment.
Perform the following procedure to replace an inlet filter:
1 Turn DataFID/MicroFID II off. Refer to section 3.10, Shutdown
DataFID/MicroFID II, on page 3-55.

2 Turn the hydrogen fuel cylinder to the CLOSED position.
3 Unscrew the inlet filter housing from the inlet. (See Figure 5-1.)

DataFID/MicroFID II Operating Manual

5.4 Replacing the Exhaust Frit Filter and Housing
The exhaust frit filter and housing (PN A3201116) can become clogged with finecarbon ash produced from burning vapors and gases which exit from the detector.
It may also be clogged by excess humidity generated in the flame ionization
process. Clogging of the exhaust frit filter and housing will significantly reduce thesample flow through the instrument causing a flame out or flame ignition difficulty.
Inspect the exhaust frit filter and housing regularly or when there is difficulty inignition or maintaining the flame. If it is found to be clogged, replace it with a new
exhaust frit filter and housing. If sampling in a hot and humid environment, or
when sampling high concentrations of organic vapors and gases, the exhaust fritfilter and housing may need to changed more often. If DataFID/MicroFID II is usedinfrequently, the filter may only need to be changed once every 3 to 6 months.
Perform the following procedure to replace an exhaust frit filter:

1 Turn DataFID/MicroFID II off. Refer to section 3.10, Shutdown
DataFID/MicroFID II, on page 3-55.
