This course will explain Standard Test Methods for Determination of Gaseous Compounds by Extractive Direct Interface Fourier Transform Infrared (FTIR) Spectroscopy, including US EPA’s Stack Testing Method 320, “Vapor Phase Organic & Inorganic Emissions by Extractive FTIR.”  FTIR measurement data are used to evaluate process conditions, emissions control devices, and for determining compliance with emission standards or other applicable permits.

This field test method employs an extractive sampling system to direct stationary source effluent to an FTIR spectrometer for the identification and quantification of gaseous compounds. This test method is potentially applicable for the determination of compounds that (1) have sufficient vapor pressure to be transported to the FTIR spectrometer and (2) absorb a sufficient amount of infrared radiation to be detected. 

This field test method provides near real time analysis of extracted gas samples from stationary sources. Gas streams with high moisture content may require conditioning to minimize the excessive spectral absorption features imposed by water vapor.  This method also requires the preparation of a source specific field test plan. The test plan must include the following: (1) the identification of the specific target analytes (2) the known analytical interferents specific to the test facility source effluent (3) the test data quality necessary to meet the specific test requirements and (4) the results obtained from the laboratory testing.




• Principles of FTIR including a technical explanation of FTIR measurement principles

• Overview of the FTIR stack test methods

• A comparison between the two FTIR methods

Core Material & Principles

• Applicability, interferences, limitations to use, detection levels, etc.

• Comparison to other VOC methods

• Calibration and quality assurance procedures

• Differences between makes/models of analyzers and what to look out for as well as the advantages and disadvantages of different equipment

what to look for

• What to consider in reviewing a protocol

• Some compounds don’t have standards available for spiking with, so surrogates are used. Training will include guidance on how to select the proper surrogates.

• What to look for in observing the testing, including recommended observer record-keeping

• What to look for when reviewing the data from the testing (the report)

• FTIR validation steps and what to look for regarding that in the field.

Hands-on Material

• A physical demonstration of an FTIR analyzer with hands on participant training

• Calculations – including a hands-on exercise performing appropriate calculations

• Sample vs. calibration gas temperatures, pressures, and other settings that impact results

• Tips, tricks and pitfalls

Parting Words

• Safety and health considerations and recommendations

• USEPA guidance and information documents, including their electronic locations (URL)

Target Audience

 State and local agency staff from MARAMA member agencies that conduct or observe emissions source tests in order to quantify emissions and assess compliance with local, state, and federal requirements.
