The Portable FTIR Gas Analyzer The Gasmet DX4040 analyzer combines Fourier transform infrared (FTIR) spectrometer, rhodium-gold coated sample cell, built-in sample gas pump and signal processing electronics in a compact unit. In battery use, operating time is 2.5 hours with one charge. AC power supply is also included. There is a filter for particulates inside the probe and no sample preparation is needed. The lightweight analyzer can be used with or without the durable Teflon coated backpack. The Gasmet DX4040 is designed for on-site measurements of different compounds (both organic & inorganic) at low concentrations in ambient air. Typical usage areas include industrial hygiene and emergency response situations. The communication between the analyzer module and the PDA is wireless (with Bluetooth protocol). In the standard configuration, concentrations of 25 gases of interest can be simultaneously monitored. Furthermore, with the optional Calcmet 4040 Professional software the analyzer can be connected to a laptop PC for extended analysis capability (e.g. identification of unknown compounds with library spectra). There are no consumable parts that would need replacing on regular basis. In addition, due to FTIR technology, the calibrations remain very stable. Hence no span calibrations are needed. Also, cross-interferences (i.e. interference from other gases) are automatically compensated in the analysis algorithm during the calculation of the results. To sum up, the Gasmet DX4040 provides a very cost-effective, easy-to-use solution for multicomponent gas analysis in ambient air. STREET ADDRESS: Pulttitie 8 A 1 00880 Helsinki, Finland
