An open-path Fourier transform infrared (FTIR) spectrometer system that has automated algorithms for quantifying volatile organic compounds in industrial settings is available from Optra Inc. Features include an encoder-based reference system, an uncooled pyroelectric detector and a plastic injection-molded retroreflector array. The 8-cm21 system exhibits low spectral resolution and operates over the 7- to 14-µm range. The module, including the telescope, measures 10.5 × 8.5 × 7.25 in., weighs 14 lb and comes with two PCI boards. Operation is controlled via a graphical user interface that presents the molecular concentrations and warns if any are above OSHA's permissible limit.
