Section 1: INTRODUCTION 

1.1 Summary of Test Program

Exhaust emission testing was performed on one (1) reciprocating internal combustion 

engine in Tulsa County, OK. Nordon Corporation of Round Rock, Texas, performed the 

exhaust emission testing on March 5, 2010. 

This emission testing was performed to determine the formaldehyde (CH2O) 

concentrations from the exhaust of the engine for in-house data. The testing was 

performed while the engine was operated at two engine load conditions (94% and 1% O2

and 81% and 2% O2). The concentrations of oxygen (O2) were measured to correct the 

concentration of formaldehyde to 15% O2. The test methods used followed the principles 

and procedures set forth in the Code of Federal Regulations, Title 40, Part 60, Appendix 

A, Method 3A and Code of Federal Regulations, Title 40, Part 63, Appendix A, CTM323.

Section 3: SUMMARY AND DISCUSSION OF TEST RESULTS

3.1 Objectives and Test Matrix

The purpose of the test was to measure CH2O and O2 concentrations from the exhaust of 

one 380 cubic inch (6.2 Liter) four-stroke rich burn engine without post-combustion 

controls 

Specific objectives:

• Measure the concentrations of CH2O and O2 from one (1) reciprocating internal 

combustion engine. 

• Two impinger trains (Train A and B) were used to collect samples to be used to 

measure CH2O concentrations from the exhaust of the engine. The two samples 

were collected during each run for duplication purposes.

• Perform emission sampling at 2 different engine load conditions (94% and 1% O2

and 81% and 2% O2).

3.2 Presentation of Results

The results of the testing are presented in a tabular format in Tables 3-2 and 3-3. These 

tables include all the relevant information pertaining to the engine operations, emissions, 

and ambient conditions. CH2O concentrations are presented in ppmv and ppmv @ 15% 

O2. O2 concentrations are presented in % by volume. Nordon Corporation personnel 

collected relevant engine operational data.

3.3 Field Test Changes and Problems

A deviation of CTM-323 was performed during formaldehyde sampling by using a 

critical orifice rather than a dry gas meter to determine sample volume. Nordon followed 

40CFR60 Method 6 procedures for the orifice sampling. This approach was taken due to 

the greater sampling accuracy provided by the orifice at the required sample rate of 0.2 to 

0.4 liters per minute.

No problems were experienced.

Section 4: SAMPLING AND ANALYTICAL PROCEDURES

4.1 Test Methods

EPA Method 3A- Determination of Oxygen Concentrations (Instrumental Analyzer 

Procedure). An analyzer equipped with a paramagnetic cell was used to perform this 

method.

EPA Conditional Test Method 323 from 40CFR63- Measurement of Formaldehyde 

Emissions from Natural Gas-Fired Stationary Sources—Acetyl Acetone Derivitization 

Method. The CH2O concentration is determined by the reaction of the sample to acetyl 

acetone. A colored derivative is created which is measured colorimetrically. A Thermo 

Scientific Spectrometer was used to determine the percent transmittance.

4.2 Instrumental Sample System

The instrumental sample system is used to collect samples for the determination of O2

concentrations. A stainless steel sample probe is used to extract exhaust gas samples 

continuously throughout each test run. Sample gas enters a sample probe and continues 

into a stainless steel electronically actuated solenoid 3-way valve. The 3-way valve is 

used to perform leak checks and sample system bias checks. From the valve, the gas 

flows through a 3/8" Teflon® heat traced sample line to a stainless steel minimum 

contact condenser to dry the sample. From the condenser, a 3/8" Teflon sample line 

brings the exhaust gas to a manifold in the mobile analysis unit via a Teflon-lined 

diaphragm pump. A manifold partitions the gas through quick-connects so that each 

instrument can directly sample exhaust gas. Each instrument is equipped with a 

rotameter to maintain correct sample pressure and flow rate. Each instrument is 

connected to an analog to digital USB converter and connected to a computer to 

document its response during calibration, quality assurance and control, and testing. 

Figure 4-1 provides an instrumental sample system diagram. 

4.3 Impinger Sample System

The impinger sample system is used to collect sample for the determination CH2O

concentrations. A sample pump attached to a calibrated orifice is used to draw a sample 

through an impinger train containing reagent grade deionized water. The impingers are 

submerged sufficiently in an ice bath to absorb formaldehyde in the reagent water. 

Figure 4-2 provides a schematic of the sample trains A and B.

4.5 Other Test Equipment 

Data Acquisition System- A National Instruments Model 6008 USB data acquisition 

board was used to convert the instrument’s analog signals to digital signals. The data was 

then recorded on a computer running Labview software. The data acquisition records are 

located in Appendix F of this report.

Wet/dry bulb psychrometer- Determination of ambient temperature and humidity.

Aircraft-type aneroid barometer- Determination of absolute atmospheric pressure.

Section 5: QUALITY ASSURANCE ACTIVITIES

5.1 QA Continuous Analyzers (Methods 3A)

Calibration Error Check- Prior to and following each run, each continuous emission

monitor's linearity response was checked using calibration gases. The instruments were 

calibrated at zero (nitrogen), and then calibrated at the high end of the scale. Next, an 

intermediate calibration standard was introduced to each analyzer to check the 

instrument's response. The instruments were considered linear when their responses to 

the calibration gases were ±2% of the calibration standards as per the EPA Reference 

Methods. 

Sample System Leak Check- Prior to sampling, a leak check was performed on the entire 

sample system. The sampling system demonstrated the ability to hold at least a 10"Hg 

vacuum before and after the testing. The sample system held the vacuum for one minute 

with no vacuum loss for the pre-test. 

Sample System Bias Test- A sample system bias test was also performed by introducing 

the zero gas and the calibration gas that closely approximates the stack effluent for each 

analyte. The sample system meets the bias specification if the difference between the 

calibration error check and the sample system bias check does not exceed ±5%. 

Zero and Calibration Drift Assessment- A zero and span calibration drift assessment was 

performed after each test run. The analyzer will be considered valid if the analyzer’s 

response does not drift more than ±2% of the span for either the zero and calibration gas 

over the duration of each run.

Calibration Gas Certifications- The calibration gases used for the O2 checks have been 

analyzed and certified by the vendor as being ±2% accurate. The O2 Run QA in 

Appendix D document the calibration checks performed.

5.2 QA Formaldehyde Sampling and Analysis (CTM- 323)

Sampling QA- Reagent grade deionized water was used to absorb CH2O during the 

sampling. Leak checks were performed on each formaldehyde sampling train prior to 

and after sampling. A field blank sample was collected during the sampling and analyzed 

in the same manner as the field samples. A calibrated orifice was used to determine the 

amount of sample gas volume during each run. A post-test orifice check was performed 

upon completion of the project.

Laboratory Analysis QA- Reagents were prepared the week of the test. A calibration 

curve was performed, and a correlation coefficient greater than 0.99 was observed. 

During CH2O analysis, samples spikes, lab blanks, and lab duplicates were performed 

and analyzed in the same manner as the field samples.
