A new multichannel gas analyzer based on ion - neutral interaction principles is introduced. This gas phase secondary ion mass spectrometer using several well defined energy levels for the ionization process quantitatively analyzes gas mixtures without the use of presetection techniques. A high sensitivity for many compounds together with high cycle rates allows dynamic studies of gaseous emission in the low and sub ppm range. Transient studies of inorganic compounds like NO, NH3, H2S, COS and SO2 in catalytic converter systems and differentiated Hydrocarbon analyses of C1 to C8 prove the versatility of the instrument.
