    Abstract: PROBLEM TO BE SOLVED: To obtain improved analysis pipe and method for detecting a number of selected impurities in the gas flow of a mixed gas under continuous gas flow conditions. SOLUTION: A discharge pipe 10 is improved for use in a gas discharge spectrometer for analyzing and measuring a plurality of low-concentration gas/vapour impurities in a gas flow, has a plurality of analysis points 16, 18, 20, and 22, and analyzes and measures emission radiation being generated by an AC power supply across sample cells 24 and 26 through them.

    Abstract: An electric discharge tube for a gas emission spectrometer and method for analyzing and measuring low concentration levels of multiple gas/vapor impurities in a gas stream under continuous flow conditions. The electric discharge tube comprises a plurality of analytical sites through which emissive radiation generated by an alternating source of power across the tube can be analyzed and measured.

    Abstract: An analyzer suitable for performing continuous gas analysis in ultra-high purity applications. The analyser combines a low-level emission source and a gaseous emission spectrometer (10) having a charge coupled device (CCD) diode array as a detector. The CCD detector replaces one or more photomultipliers and narrow bandpass filters typically used in spectrometers. The analyser performs various processing operations to evaluate and eliminate the effect of background light level, or dark spectrum.
