| Abstract |
Split and splitless injections are gas chromatographic techniques that introduce the sample into a heated injection port as a liquid, and then rapidly and completely vaporized the sample solvent as well as all of the analytes in the sample. The vaporized sample is transferred to the head of the GC column. This work demonstrates a miniature split/splitless injection system for quantitative determinations of liquid sample mixtures in GC analysis. The injector temperature is adjustable from ambient to 300℃. The split flow is adjustable by means of flow/pressure sensors and a precision proportional valves. System performance will be discussed in terms of the selectivity and sensitivity of GC separation. Split/splitless injector is expected to be used for a portable GC instrumentations.
