A VALVELESS GAS CHROMATOGRAPHIC SYSTEM WITH PULSED INJECTION AND TEMPERATURE PROGRAMMED ELUTION

摘要

A portable gas chromatograph includes a sample adsorbing ribbon (220) having asampling position (205) and second desorbing position (206). The sample isdesorbed by activating heaters (210, 211). The desorbed sample passes to achromatography column (209b) which is then heated by a third heater (212). Theseparated sample is passed to a detector (213) for analysis.
