OPTRA proposes the development of a high speed resonant Fourier transform infrared (FTIR) spectrometer for surface contaminant detection via thermal luminescence. The system will generate 10,000 spectra per second over the 7-14 m spectral range at 8 cm-1 spectral resolution; the NESR is projected at 4×10-9 W/(cm2•ster•cm-1) over a 100 s integration time. The key to the system is a res ...

Trace detection usually requires a vapor concentrator that collects dilute analytes from a vapor sample and delivers them at a higher concentration to the detector. Conventional vapor concentrators tend to use either cryogenics, where vapors are concentrated on a cooled surface and then desorbed via flash heating, or sorbent technology, such as zeolites, where vapors are absorbed before flash-hea ...
