Automatic gas-chromatographic determination of light hydrocarbons and sulphur compounds in air
conference paper
This paper describes an apparatus developed by the Central Laboratory of DSM, Heerlen, The Netherlands, which is essentially a combination of two gas chromatographs; one for the determination of sulfur carrying components and one for determining the light hydrocarbons. It was considered desirable to combine these into one unit, because this would eliminate the need to duplicate certain items of equipment such as the feed system for purified air and hydrogen, the thermostat, and the programmer. Analog signals from the chromatographs are converted to digital signals and stored in a memory. After termination of the two analysis cycles, the digital signals are read out and compiled in an analysis report.
