1.0 Introduction
Tests will consist of (3) 60 minute test runs.
The test will be conducted using a multi component gas analyzer that incorporates a Fourier Transform Infrared (FTIR) spectrometer. FTIR is state of the art technology. It is
designed to military specifications and allows simple calibration using only single component calibration gases.

3.0 Method Synopsis
For all stacks greater than 6" in diameter, GAS will sample at 3 points within the stack. These points will be located at 83.3%, 50%, and 16.7% of the
stack diameter.

2 diameters downstream

The purpose of the method is to provide guidance for the selection of sampling ports and traverse points at which sampling for air pollutants will be
performed pursuant to regulations set forth in this part. Method 1 may be modified as allowed in Subpart JJJJ & ZZZZ. Alternatively, for NOx, CO,
VOC, O2, and moisture measurement, ducts ≤6 inches in diameter may be sampled at a single point located at the duct centroid and ducts >6 and
≤12 inches in diameter may be sampled at 3 traverse points located at 16.7, 50.0, and 83.3% of the measurement line ('3-point long line'). If the
duct is >12 inches in diameter and the sampling port location meets the two and half-diameter criterion of Section 11.1.1 of Method 1 of 40 CFR
part 60, Appendix A, the duct may be sampled at '3-point long line'; otherwise, conduct the stratification testing and select sampling points
according to Section 8.1.2 of Method 7E of 40 CFR part 60, Appendix A."
For all stacks greater than 6" in diameter, GAS will use a sampling port that is located at a minimum of 2 stack diameters downstream from any
disturbance, and 1/2 stack diameter upstream from any disturbance.

4.2 Test Quality Objectives
EPA Method 2/2C
EPA Method 3A
This method is applicable for the determination of the average velocity and the volumetric flow rate of a gas stream. Method
2 will be used for stacks greater than 12 inches. Method 2C will be used for stacks with a diameter of 12 inches or less.
This is a procedure for measuring oxygen (O2) and carbon dioxide (CO2) in stationary source emissions using a continuous
instrumental analyzer. Quality assurance and quality control requirements are included to assure that the tester collects data
of known quality. Documentation to these specific requirements for equipment, supplies, sample collection and analysis,
calculations, and data analysis will be included.
NO 1875-2138 0-1000 ppm 0.20 ppm 2 ppm
This extractive FTIR based field test method is used to quantify gas phase concentrations of multiple target analytes from
stationary source effluent. Because an FTIR analyzer is potentially capable of analyzing hundreds of compounds, this test
method is not analyte or source specific. The analytes’ detection levels, and data quality objectives are expected to change
for any particular testing situation. It is the responsibility of the tester to define the target analytes, the associated detection
limits for those analytes in the particular source effluent, and the required data quality objectives for each specific test
program. Provisions are included in this test method that require the tester to determine critical sampling system and
instrument operational parameters, and for the conduct of QA/QC procedures. Testers following this test method will
generate data that will allow an independent observer to verify the valid collection, identification, and quantification of the
subject target analytes. A heated sample line is used to collect the sample on a wet basis per ASTM D6348. Effluent
Moisture content is determined to within a 2% accuracy using the FTIR analytical algorithm.

Control Panel: Allows the control of flow throughout the system as required by ASTM D6348 and
Method 3A. Allows for introduction of calibration standards into the sampling system at the probe
outlet, upstream of the primary particulate filter.
Due to the remote location of the source unit, additional health & safety precautions will be observed such as
avoidance of slips, trips, falls, and heat exhaustion.
Figure 9.0 Sampling Schematic Diagram
Figure 9.0 Schematic Diagram
In addition, GAS will use the following safety equipment:
O2 Sensor: Zirconium Dioxide sensor to measure Oxygen per method 3A.
Gasmet FTIR: FTIR Analyzer for use with ASTM D6348
Flow Meter: Allows proper measurement of flow.
Data: Data acquisition system that allows for the acquisition of the infrared data, Oxygen data and
analysis of the resulting spectra.
Gas: Required calibration gases per ASTM D6348 and Method 3A.
8.0 Health and Safety Concerns
In accordance with 40 CFR Part 60.8, the client must provide safe access to the unit for testing and observance.
Due to the nature of the source and the exposure to high temperatures, extreme caution will be observed in
order to avoid contact with the unit which may result in burns and or inhalation of exhaust emissions. GAS
personnel will sign in and out at all facilities, as well as undergo site specific safety training.
Probe: Heated probe assembly required by ASTM D6348.
Heated Line: Used for "Hot/Wet" sample to keep line above any dew point that would cause
moisture to drop out.
PSS: Allows precise heating of the sampling system.
