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.
