  • Gas Analyzers of MKS GAS Analysis:
    The MultiGas™ 2030 HS gas analyzer is a high resolution FTIR based gas analyzer designed to monitor automobile, diesel and catalyst combustion exhaust at 5 Hz sampling frequencies. The analyzer is designed to allow gas flows up to an exceeding 100 L/min with no back pressure or acoustic gas cell noise generated that could degrade the quantitative measurement. Twenty plus (20+) gases can be quantified simultaneously at this frequency without any reporting delays. Samples containing up to 30% absolute water content can be monitored without chillers by maintaining the gas temperature and appropriate particulate filtration. Detection limits of 1 ppm or less are achievable with this analyzer by using higher sensitivity narrower range MCT detectors. The system comes calibrated for 1 atm gas pressures at both 150°C and 191°C (for diesel applications).
    The MultiGas™ 2030 HS analyzer is composed of a high speed 0.5 cm-1 process-hardened FTIR spectrometer. The spectrometer is coupled to a patented 5.11 m high- optical-throughput 200 mL gas sampling cell with 1/2 inch plumbing to reduce backpressure and allow for higher flows. The analyzer generally incorporates a high sensitivity liquid nitrogen cooled MCT that can maintain cryogenic temperatures for up to 12 hours on a single charge. The system is delivered complete with easy to use software and health diagnostics, calibration, installation and training.

  • Gas Analyzers of HORIBA:
    Simultaneously measures CO, unburned HC (as n-hexane), and CO2 in automotive exhaust, using NDIR technology. Highly reliable with a long service life, BE-140 AD is certified for the three-gas portion of BAR-97 when incorporated into an exhaust-gas analysis system with sampling and control functions.
    Consists of solid-state infrared detectors, a microprocessor, and miniature mechanical components in a compact package. An optional galvanic cell measures O2. The unit can be wired for NO measurements, using either BE-220 or a electrochemical sensor.
    The microprocessor provides fully calibrated gas concentration values with compensation for atmospheric-pressure changes.
