Qualitative Limits of Detection of Specific Compounds Obtained by Trapping Gas Chromatograph Fractions with an Activated Charcoal Capillary and Analyzing with the Mass Spectrometer
Qualitative identification of gas chromatograph. (G.C.) fractions has created problems for the organic chemist. One of these concerns the Limit of detection for any given compound which can be achieved with a method designed to trap a G.C. peak for further analysis. This paper presents the limits of detection found attainable in the qualitative analysis of specific organic compounds. These limits were established by utilizing an activated charcoal capillary to trap the G.C. fraction prior to introduction into a Bendix Time-of-Flight mass spectrometer via the hot filament probe.
