Air Bag

The Air Bag method analyzes the effluent emitted during the air bag inflation. Detection limits assume a collection time of 2 minutes with a room-temperature DTGS detector.

Compressed Breathing Air

The Compressed Breathing Air (CBA) method analyzes CBA for impurities. This method is used with the 10 meter gas cell. Detection limits assume a collection time of 2 minutes with a room-temperature DTGS detector.

Exhaust

Gasoline: Raw Exhaust method is designed for spark-ignition engine combustion analysis where gasoline is the fuel. The raw exhaust method covers concentration ranges found in the exhaust gas without dilution. The combustion gas sample is taken either before or after the catalytic converter. This method is configured with the Thermo Scientific 2 meter gas cell and a liquid-nitrogen cooled MCT-A detector. Detection limits are based on a 3-second sample time.

Diesel:
Diesel exhaust differs from spark-ignition engine exhaust due to excess of air, leading to difficult-to-meet NOx reduction targets. FT-IR is an excellent technique to study Selective Catalytic Reduction (SCR) compounds, including NO, NO₂, N₂O, and NH₃.

Fire Science

The Fire Science method is configured to analyze toxic gases in the combustion of building materials. The method can be used with cone calorimeters, smoke boxes, or ambient sampling of combustion experiments. A corrosive-duty stainless-steel gas cell, such as the 2 meter or 10 meter gas cell, is recommended for this analysis. The 2 meter cell is recommended in all applications where the sample concentration is greater than 2 ppm; the 10 meter cell is recommended when analyzing samples below 2 ppm. Detection limits are based on a 3-second sample time with a liquid-nitrogen cooled MCT-A detector.

Renewable Energy

FTIR is an excellent technique for analyzing gases generated by new renewable energy developments, such as such as pyrolysis of wood chips or anaerobic digestion of garbage or manure. Synfuels and biogases produce environmental emissions, methane along with other potentially harmful gases, for power generation. They also cause harmful effects on the combustion chambers or compressors.

FT-IR spectroscopy offers powerful capabilities to analyze synfuel and biogas components, enabling researchers to optimize their gas generation and collection techniques.

Specialty Gases  

Gas applications which require high accuracy and stable calibrations take advantage of FTIR strengths. Used by specialty gas manufacturers, semiconductor purity testing, and ID of contaminants in O₂ or breathing air.
