Sampling and analysis of fire effluents is an important part of assessing both the environmental impact and the threat to life caused by fires. Detailed knowledge about the composition and concentration of fire effluents is required to gain a good understanding about the potential impacts of fires and for efforts to diminish these impacts.

Testing the composition of these fire effluents presents a challenge for the analytical equipment used to measure the gases. The amount of species and concentrations of interest is very large, and the harsh environment presented by the fire effluents is a challenge for the sampling.

Extractive FTIR systems is a logical solution for measuring the composition of fire effluents. The unparalleled ability to measure a wide range of species of interest and the ability to take a representative sample by hot extractive sampling makes this technology a vital part of fire testing systems.
