MultiGas™ 2030 HS 5Hz Combustion Analysis

Part Number: MultiGas 2030-HSProduct Details


The MultiGas™ 2030 HS is a high resolution FTIR based gas analyser designed to monitor automobile, diesel and catalyst combustion exhaust at 5 Hz sampling frequencies. The analyser 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 analyser 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 analyser is composed of a high speed 0.5/cm process hardened FTIR spectrometer. The spectrometer is coupled to a patented 5.11m high-optical-throughput 200 mL gas sampling cell with ½ inch plumbing to reduce backpressure and allow for higher flows. The analyser 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.

Designed specifically for process and environmental monitoring, the 2102 Process FTIR Spectrometer is compact and rugged. Capable of operating at spectral resolutions up to 0.5/cm, it is the fastest, most sensitive and stable process FTIR available. In addition, it can operate in hostile environments with a high degree of immunity to vibration and temperature changes. An advanced, high-speed data procesing system is standard, and provides low-noise infrared spectra for analysis.

This spectrometer is coupled to a patented low volume (200mL) multi-pas gas cell with a 5.11 meter effective pathlength. The patented design of this cell incorporates aspheric, aberration-correcting mirrors which provide the more than twice the optical throughput of a conventional multi-pass gas cell. The gas cell can be set and maintained at any temperature up to 191°C. Normally it is operated at 150°C or 191°C for combustion applications.
