| Abstract: | During optimizing gas chromatography performance, the flow rate of carrier gas could be accurately adjusted by electronic pressure control (EPC) system. The principle of EPC has been introduced herein, and its application whereto sample injection and column separation was demonstrated on the analysis of pesticides by GC/MS. |
