Abstract
The development of a miniaturized mid-infrared grating spectrometer operating at in the wavelength range 8-12.5μm is reported. This measurement device can be used for detecting organic contaminants in waste water, leakage fluids, and when redeveloping contaminated soils. The spectrometer system was tested at laboratory conditions. Measurements of chlorinated hydrocarbons revealed a detection limit of 900 ppb for tetrachloroethylene.
