By using the newly designed FID micro-current amplifier and electronic pressure controllor(EPC),the high-precision detection and stream pressure control were realized for partition gas chromatograph,its minimum volume fraction of gas detection is 1 × 10-6 C1-C5 online detection performance,which expands the scope of chromatograph application,making it possible to combine with quantitative degassing technology.Digitization and real-time feedback of EPC high precision pressure control technology greatly improve the stability of partition gas chromatograph.With the new electric control and human-computer interaction system,the intelligent applications of the partition gas chromatograph were realized,and the function components within the instrument are of the modular integration were convenient for on-site maintenance.A new generation of high-precision intelligent partition gas chromatograph may provide more accurate and reliable first-hand gas logging data for the interpretation and evaluation of oil and gas reservoirs.
