Outline and Features

The moisture analyzer was designed using a super hybrid sensor (S.H.S.) adopted in ananalytical balance. Therefore, the results are more precise and get greater repeatability.
The analyzer using the S.H.S. has high sensitivity, needs only a sample quantity ofa few grams, and the analysis time becomes shorter.
A 400W halogen lamp is used as the heating source and the temperature on thesample pan can reach 200°C within two minutes.
There are five analysis modes.
Standard mode .....The moisture content can be obtained with settings of thedrying temperature and accuracy.
Quick mode ...........Sample is heated up for approximately three minutes at 200°C sothat analysis time becomes shorter. The moisture content canbe obtained with settings of the drying temperature andaccuracy.
Automatic mode .....When the change of moisture content per minute is less than thepreset termination value, the measurement is automatically stopped
and the result is obtained.
Timer mode .............The sample is dried for a preset time and the result is obtained.
Manual mode ..........This mode can stop the measurement by key operation and theresult is decided.
The heating patterns can be used for analysis modes other than the quick mode.
(For ML-50, standard drying and quick drying can be used only)Standard drying......Maintains a constant drying temperature.
Ramp drying ...........Increases the drying temperature gently.
Step drying..............Uses multiple steps of the drying temperature.
Quick drying ...........Heats up to 200°C for few minutes and uses a constant drying
temperature.
The analyzer can store and recall proper individual settings for each sample using a
program number (PROG No.).

temperature (Use temperature calibrator for MS-70 and MX-50 except MF-50 andML-50). The analyzer can output the data required at GLP, GMP and ISO at the endof the calibration.
The analyzer has a self check function that can detect function errors.
The analyzer displays the current change of moisture content per minute [%/ min] inreal time. It can be used for the reference to find the analyzing mode.
The sample pans can be used repeatedly.
The sample pans and the disposable aluminum foil pans are included in thestandard accessories.
There is a test sample that is used to check the moisture accuracy. (The test sample
is a part of the standard accessories except for the ML-50)
The glass fiber sheets can be used for quick and precise measurement of a liquidsample. (The glass fiber sheets are a part of the standard accessories except for
the ML-50)
A reference card is built into the bottom of the analyzer.
Principle and Use
The moisture analyzer, based on the principle of thermogravimetric analysis, dries asample using a halogen lamp and obtains the moisture content in % and otherresults by the difference between the wet weight and dry weight.

5.3.1.

Operation of the Sample

Use a proper sample quantity. If the quantity is small, precise results may not be possible.
If the moisture content of the sample (example: plastic) can be estimated to be lessthan 1%, the mass of moisture is not enough for the measurement and the result
may not be accurate. Consider the following sample mass for the measurement.
An estimate of moisture content
1%
0.5%
0.1%
Necessary mass for measurement
2 g at least
5 g at least
20 g at least
If the measurement is repeated, maintain the same sample quantity.
Crush grain samples to a small, uniform powder for a quick drying process.
Spread the sample as evenly as possible.
The analyzer is designed to measure the moisture content
No goodGoodof the sample by its weight change. If the sample contains
volatile matter, it may vaporize during drying causing a measurement error.
When measuring a liquid or liquid state sample that may make a film on the surface,
we recommend you use a glass fiber sheet (AX-MX-32-2). Refer to “5.3.3. Glass
Fiber Sheets”.

5.3.2.

Operation of the Analyzer

Press the RESET key to display the zero value before
each measurement.
0.000gCheck that the displayed sample weight is stable before
measurement. Press the
START
key to start ameasurement.
2.02
5.43% %/min
Select the proper analysis mode to finish a measurement.
Use the change of moisture content per minute [%/min] that isResult display
displayed during measurement as a reference value.
The analyzer needs a pre-heating process before measurement. When measuring
samples repeatedly or continuously, the first result is always different from the others.
The pre-heating process is as follows: Put a sample pan, instead of a sample, on thepan. Press the START key to heat it. The analyzer temperature becomes equilibrium.
Use a sample on the sample pan that has cooled to room temperature. When a sample
is put on a hot sample pan, the moisture content is diffused before measurement, andprecise results are not possible. We recommend you use multiple sample pans.
Do not pile up sample pans during a measurement.
Avoid drift and vibration of air conditioners. It may cause "measurement error" and"unstable value". In particular, because MS-70 is sensitive instrument, it isnecessary to consider these influences.
When the difference between ambient temperature and sample temperature issmall, it may cause temperature control error.
Example: If the drying temperature is set to the range of 30°C and 50°C, it isaffected by room temperature.
Check the activation of the halogen lamp with the operation indicator.
Example: If low drying temperature is set, the brightness of halogen lamp becomes dark.
Check the activation
with blinking

Glass Fiber Sheets

Use the glass fiber sheet to measure the moisture content ofsamples as described in the following examples. When thissheet is used, vaporization of moisture is speeded up andmoisture measurement result becomes quick and precise.
This accessory (AX-MX-32-2) is a package of 100 glass fiber sheets.
This accessory is inclued in the packing for MS-70, MX-50 and MF-50.
Purchase this accessory by your order for ML-50.
Use the glass fiber sheet (AX-MX32-1) for high surface tension liquid samples.

Example 1: "Liquid Sample" Or "Meltable Sample"

When the glass fiber sheet is used for these measurements, moisture is more apt tovaporize because of expanding the surface area and space. And the glass fiber
sheet has the effect of preventing a surface film from forming at drying process.
A sample containing a lot of moisture: Milk, yogurt, soybean milk, condensed milk, ketchup, resin, liquid paste, hand soap, etc.
A sample that melts and adheres to the sample pan.
Example:Chewing gums, caramel, hony, etc.

Procedure (Preparation before heating)
1 Put the glass fiber sheet on the sample pan.

Example 2: "If the Sample's Surface is Apt to Carbonize"

When the sample is covered with a glass fiber sheet, carbonization of the sample surface
decreases. Therefore the measurement result becomes repeatable and precise.
A sample including a lot of sugar, protein and oil

Sample pan

Example:Hony, soybean powder, green tea leaves, cookies, etc.
A sample that has dark surface and is apt to carbonize
Example:Coffee, peanuts, etc.

8.2. Test Sample (Sodium Tartrate Dihydrate)---Test Sample (Sodium tartrate dihydrate, Na2C4H4O6•2H2O )--Sodium tartrate dihydrate is used to check the accuracy of measurement for the
analyzer.
As an ideal substance on theory, sodium tartrate dihydrate, has a moisture content
of 15.66% in the molecule. But the moisture content may change depending on
storage conditions.
The moisture content of 15.0 to 16.0% is obtained by the method below.
(Unit % is based on wet sample)
Sodium tartrate is contained in food (example : wine). If it may irritate the eyes andnose, wash with water.
The test sample cannot be used repeatedly. Dispose of it as flammable matter.
In case of MS-70 MX-50 and MF-50, test sample is included in these packing list.
In case of ML-50, purchase the test sample of accessory.
Caution A hot sample pan may cause an error. Allow the pan to cool before the next test.

12. Calibration
The moisture content is calculated with a ratio of wet weight and dried weight.
Therefore, the absolute value of weighing does not influence the calculation of the
moisture content, but it is necessary to get precise weighing for GLP, GMP and ISO.
Use a 20g mass or a 50g mass to calibrate the weighing sensor.
When calibrating the weighing sensor, you can output the calibration report adapted
to GLP, GMP and ISO.
There is a certified temperature calibrator (accessory AX-MX-43, only for MS-70 and
MX-50) to calibrate the pan temperature for precise temperature control.
When calibrating the temperature, you can output the calibration report adapted to
GLP, GMP and ISO.
The analyzer can store an ID number to be used in the calibration report. The
number can be used for management and maintenance of the analyzer

12.1. Identification Number (ID No.)The ID number consists of the following seven characters.

A standard mass of 20g or 50g can be used for the calibration
A 20g standard mass (AX-MX-41 or AD1603-20F1) is recommend.
CautionAvoid vibration and drafts that affect the calibration. If affected, the analyzer
may be unable to calibrate the weighing sensor.
Use a 20g mass for the calibration, because the height between the weighing
pan and glass-housing is 26 mm. If a tall mass is used, open the glass-housing
and avoid external influence.
