In-Cell Emission Measurement and Testing

BEX-1000FT, a multi-component emissions analyzer based on Fourier Transform Infrared (FTIR) technology, allows for the continuous raw or dilute measurements of up to 40 gases using one device, which allows the system to replace multiple conventional analyzers. Since there is only one detector, there is only one time delay to handle –compared to multiple time delays when using numerous conventional analyzers. BEX-1000FT is a standalone option for a FTIR gas analyzer and key piece of emissions measurement equipment. The standard system operates at vacuum pressure which allows for a fast-response time and lower consumption of the exhaust gas. It can also operate at atmospheric pressure, thus providing a more tailored approach to sample acquisition.

  • Provides asynchronous measurement of over 30 regulated and unregulated gases at one detector
  • Vacuum sampling system that allows for decreased absorption, a fast response rate (T10-90 -approximately 1.5 sec) and a lower consumption of the exhaust sample
  • One device that replaces multiple conventional analyzers, with only one time delay to consider for dynamic analysis
  • Optional roll cabinet available to provide easy sharing between test cells
  • Designed to provide continuous measurement of undiluted (raw) vehicle exhaust for gasoline, diesel, CNG and alternative fuel vehicles
  • Low-cost operation due to drift-free calibrations and minimal maintenance requirements
  • A single device that measures all gasses imperative for emissions regulations as well as engine and catalyst calibration and development

  • Differentiated measurement of NO, NO2, N2O, CO, CO2, CH4, NH3, hydrocarbons, alcohols and carbonyls
  • Sample acquisition rate up to 5Hz
  • An advanced cross-interference compensation routine, significantly minimizing the influence of water and other interfering gasses
  • High Pressure Control system, allowing for sampling in high-pressure, sample-inlet conditions
  • Meets or exceeds all requirements specified for FTIR Measurements by US EPA, ASTM, ISO and Euro VI HDD
  • Vacuum sampling method allows for a faster response rate (T10-90<1.5 sec), and a lower consumption of the exhaust sample
  • Easy integration into automation systems via AK interface
  • Transportable analyzer that allows for test cell sharing
  • Gas analysis methods for different fuel types, including gasoline, diesel, CNG, and other alternative fuels
  • Low-cost ownership due to drift-free calibration and minimal maintenance requirements
  • One physical analyzer with one delay time to simplify the measurement process
  • Excellent correlation with conventional analyzer systems
