SMM/THz Gas Sensors

A SMM/THz gas sensor needs a core spectrometer, such as described in Section V.C, packaged with a gas sampling system and appropriate operations software. We have recently described such a system [1]. The sensor is self-contained, including gas handling and computation, in a standard 19 in equipment rack format, with a height of 5.25 in and a depth of 18 in. Its core spectrometer provides absolute specificity (probability of false alarm -10) on a mixture of 32 gases. It is capable of automated analysis with a cycle time of
