This method is used with the 10-meter gas cell. The Compressed Breathing Air (CBA) method analyzes CBA for impurities.

In addition, system-level product offerings are easily automated, providing multichannel sampling and factory reporting. FTIR can simultaneously measure a wide range of contaminants down to single-digit parts per billion, and down to double-digit parts per trillion for certain semiconductor applications, using advanced technologies like StarBoost™. Measurement of trace contaminates in N₂, O₂, H₂, Ar, Kr, and CO² used in semiconductor, medical, food and beverage and energy. Detection limits assume a collection time of 2 minutes with a room-temperature DTGS detector. The Aviator’s Breathing Oxygen (ABO) method is designed to detect impurities in ABO gas according to the US Air Force military standard 1564A. Successful ambient air monitoring requires the ability to discriminate target compounds down to single-digit ppb even in the presence of high concentrations of interferences, such as water, solvents, and hydrocarbons. Measuring challenging compounds like ethylene oxide requires technology that avoids false alarms for benign interferences and meets standards from regulatory bodies such as the Environmental Protection Agency (EPA) and US Occupational Safety and Health Administration (OSHA). The Air Bag method analyzes the effluent emitted during air bag inflation.
