Summary
In order to increase accuracy of split ratio measurements by interruption of the septum purge gas stream a gas chromatograph (GLC) sample injection system was modified by the introduction of a rapid-action gate-valve in the appropriate gas line. The effects of this modification are described. It is shown to improve the reproducibility of injected amounts in multiple analysis and thus the accuracy of quantitative determinations.
