Direct coupling of a gas chromatograph to an ion trap detector

Hyphenated Methods for Identification After Chromatographic Separation

“…This allows the position of the column end within the ion source to be adjusted for maximum ion yield [26][27][28][29][30]. This is not incompatible with the optimum flow rates of some types of open tubular columns in gas chromatography but is much less than typical flow rates for packed columns.…”
