GasmetTM FTIR application note Hazardous chemicals and materials (HAZMAT) KEY WORDS • Hazardous materials and chemicals • Fourier Transform Infrared (FTIR) PRODUCTS • DX4040 Portable FTIR Gas Analyzer • Calcmet 4040 Professional Analytical software package effects. Identification of gases in addition to the 25 is possible by connecting the instrument to a computer and searching against a large library using Calcmet 4040 Standard software. As the PDA automatically stores recorded spectra and the analysed concentrations, further analysis and verification is possible if required, and the results can be traced back to the original infrared spectra of the samples. Accidents involving chemicals and other hazardous materials require fast and accurate gas measurements as part of the first response. The DX-4040 portable FTIR gas analyzer provides reliable identification and concentration measurements of hazardous gases in 60 seconds or less. The battery powered backpack-size analyzer records infrared spectra at 10 scans/second and is capable of sub-ppm detection. The DX-4040 requires no span gas calibrations and only a short zero procedure, and it is fully operational only minutes after arriving at site. The analyzer is controlled by a rugged PDA (personal digital assistant) connected to the analyzer by either serial cable or Bluetooth wireless link. The PDA is watertight and shockproof, and proprietary Calcmet Lite software is designed so that it can be operated with a single button if necessary. The DX-4040 performs simultaneous analysis of 25 gases with compensation for cross-interference Figure 1 Gasmet DX-4040 gas analyser transported to site in a durable transit case.
