The new MultiGas 1065-Ready HiSens analyzer is an FTIR-based multiple gas analyzer designed to meet the extremely low detection limits and strict analysis criteria for certifying N2O emissions in both light duty (LD) and heavy duty (HD) vehicle and engine testing. This same system can also be easily deployed in the field for ambient air monitoring. The analyzer was tested and validated for use in EPA 40 CFR Part 1065 and 1066 as well as Euro VI certification testing on diluted gas streams for both modal and static bag emissions. The MultiGas 1065-Ready HiSens analyzer has proven to be the most accurate and stable analyzer on the market even when going head to head with state-of-the-art, laser-based systems like QCL and TLD analyzers.

Features & Benefits:

  • Single digit ppb detection of N2O per EPA 40 CFR Parts 1065 and 1066
  • High sensitivity detector with no liquid nitrogen cooling required
  • Continuous measurement at 5 Hz or 1 Hz in dilute vehicle and engine emissions stream for rapid detection of changes in effluent composition
  • Capable of measuring several target emissions at low ppb levels, including N2O, CH4, CO2, CO, H2O, formaldehyde and other oxygenated hydrocarbons
  • High N2O Selectivity and Sensitivity - No bias or sensitivity to CO, CO2 , or H2O
  • Direct analysis in effluent streams that contain up to 4% water and CO2, without the use of chillers or driers
  • Rise and Fall times of less than 2 seconds
  • Flow rates ranging from 0.5 lpm up to 30 lpm
  • Complete, integration-ready analyzer reduces complexity and ensures fast install time for a fully compliant N2O system
  • Integrated gas cell heater and pressure transducer with automatic compensation for accurate analysis
  • Patented, linearized detector ensures all instruments maintain the same calibration
  • Frequency and resolution diagnostics ensure calibration is maintained for improved accuracy
  • Low cost of ownership, easy to install with user-friendly software and methods as well as very easy to maintain

MultiGas 1065-Ready HiSens analyzer is extremely sensitive to N2O and has no cross sensitivity to 4% moisture and CO2, up to 2000 ppm CO, or other components present in gaseous fuel emissions. A recent Light Duty vehicle round robin test sponsored by the Coordinating Research Council (CRC E-103)1 performed a series of validation tests on commercially available N2O emissions analyzers (FTIR, TDL and QCL-based) which showed that the MKS FTIR was the only analyzer that was not only within 10% of the GC-ECD reference method for all tests but also showed no bias in the readings from any other component.

MultiGas 1065-Ready HiSens is an extremely sensitive and stable analyzer based upon the MultiGas 2030 HS High Speed analyzer. Capable of 5 Hz data acquisition at high resolution, the 2030 HS analyzer incorporates a new high-optical-throughput sampling cell with low overall volume and Dursan coating to minimize analyte retention. The FTIR incorporates an MCT detector that does not use liquid nitrogen (LN2) for cooling, but instead deploys a thermoelectric cooler (TEC) to give fast response and high sensitivity without the inconvenience and cost of LN2. This analyzer configuration, along with the software analysis package, allows for the accurate measurement not only of N2O but also several gases found in emission streams - all at the same time - including formaldehyde, acetaldehyde, ethanol, methanol, methane, CO2 and CO, without removal of moisture.
