FTIR Testing

Some situations call for a more complete emissions profile than a standard stack test will give you. Perhaps you need to simultaneously identify both organic and inorganic gas compounds in your emissions; or maybe you want to analyze compounds in varied situations, such as material off-gassing, exhaust emissions, or in-room air.

A Fourier Transform Infrared Spectroscopy (FTIR) is the best way to get a complete emissions profile of stationary sources. FTIR testing is a process that analyzes organic, inorganic, and polymeric materials in a gaseous compound. Infrared light goes through a sample; some of the light is absorbed, while some passes through. The way the light is absorbed leaves a sort of molecular fingerprint. We use this to identify the chemical structure and name the chemical. All this can happen in real-time.

Erthwrks uses FTIR instrumentation to do compliance testing for the following regulations:

  • RICE MACT ZZZZ (Formaldehyde)
  • US EPA CFR 40 Part 60 Subpart JJJJ (a test for Spark Ignition Internal Combustion Engines)
    – VOCs can be reported on both non-methane (NMHC) and non-methane/non-ethane(NMNEHC) basis.
  • Acetyl Aldehyde
  • HCI
  • Ammonia
  • Internal Combustion Engine Tests

Erthwrks’ FTIR equipped mobile laboratory is also capable of performing RICE MACT ZZZZ (CO reduction) and TCEQ Biennial engine tests.

  • Portland Cement Industry: HAPs – Formaldehyde, Acetyl Aldehyde, HCl and Ammonia.

Thanks to its convenience and comprehensiveness, FTIR testing is quickly becoming the preferred method of EPA compliance testing. Erthwrks has the experience and knowledge you need to effectively and efficiently monitor your emissions.
