ANALYSIS OF LIGNITE-DERIVED GASES BY AUTOMATED GAS-CHROMATOGRAPHY

The automated gas chromatographic (GC) system, which is used for the analysis of lignite derived gases, is comprised of an isothermal-multicolumn gas chromatograph and an integrator which is capable of performing the data analysis and controlling the GC operation. The gaseous sample injected into the GC is separated using the five columns in the system. The switching valves control the choice and time of the sequential use of different columns. The gas analyzer offers short analysis times as well as a simple operational procedure for everyday use. © 1979 Oxford University Press.
