Abstract: In gas chromatography, 80% of the trouble is caused by the injection system. Also here we have seen that by degradation of sample components, O-rings, back flash and septa, extra peaks can be generated. Besides this, the conditions used for injecting the sample can also produce serious extra peaks.
