5 Hz COMBUSTION ANALYSIS The MultiGas™ 2030 HS 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 and 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-opticalthroughput 200 mL gas sampling cell with ½ 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.

Spectral Analysis The MultiGas analyzer features robust quantitative analysis software, which can analyze and report concentrations for dozens of compounds simultaneously. The software, which is installed on a high speed computer, performs automatic corrections for gas temperature and pressure variations, which are measured directly by the analyzer. Samples can be acquired and analyzed in less than 0.2 seconds, making transient analysis possible. A section of the mid-IR combustion gas spectrum (white) is shown above along with quantification regions (in color and below the sample) for some...

Instrument Independent Calibration The MultiGas software features multi-point calibration curves that provide a dynamic range up to 9 orders of magnitude (ppb to 100%). Calibrations for many species are provided with the instrument, and additional calibrations can be generated by the user from gases of known concentration. Utilities in the MultiGas software verify the performance of each instrument, which allows a calibration generated on one MultiGas to be used on any other MultiGas without alteration.
