Abstract
By means of the openly combined GC(TCD)-MS(Solid Disk Enricher(SDE)-Mattauch-Herzog Type), the relation between GC-injected sample size and area of the repeated rapid scanning method fixed to one mass was discussed. A part of the GC-injected sample escapes together with helium as a carrier gas from the outlet of the column and SDE, but the amount of MS-detection is approximately proportional to that of GC-detection; the half-width of the peak of the former is approximately1. 6times as wide as that of the latter. It was confirmed that GR benzene contained0.069±0.006%of toluene as a microimpurity and that a detectable amount of toluene in the n-hexane solution was0.01%, which was3×10-5μl of toluene at m/e91as an absolute detectable amount.
