Cerex multi-gas FTIR analyzers are capable of detection of hundreds of gas compounds. Individual species are resolved and quantified through broadband spectral analysis. Broadband analysis allows flexibility to choose the absorbance peaks of interest for each gas monitored to meet application specific monitoring goals. Simultaneous analysis of multiple absorbance features for each species allows extended dynamic ranges for target gases. All Cerex FTIR analyzers may be calibrated insitu with IR absorbing primary standard gas.
