System performance.

Chemical detection range	All the 8 chemicals detected during AT.
Sensitivity	During AT, DMMP was found at LoD <900 ppb and LoI <7 ppm.; LoD and LoI depend on absorption coefficients and on correlation parameters settings. Typical values are few ppm.
Selectivity	Very strong ability to recognize targets and interferents.; All the 8 chemicals were correctly identified during AT, by comparing the experimental spectra to the full DB of 400 chemicals.
Response time	Few seconds to detect the gas.
False negative rate	No false negative during AT.
False positive rate	No false positive during AT.
Size and power needs	Size ≈30×20×15 cm; weight ≈7 Kg; power < 15 W (sensor head).
