E•Prod  GC-7860-DW(分析解決方案7860-34204)

廣譜型燃氣分析91福利片导航网工作原理:

樣品經閥進樣後,在通道I上C1-C6經過色譜柱分離,流入到FID進行檢測;與此同時在通道II上,樣品進入預分離柱,將樣品分離成C2-C6和CH4+CO+H2+O2+N2+CO2兩大組分,反吹預柱把烴類組分C2 以上放空,而CH4+CO+H2+O2+N2+CO2進入後麵色譜柱分離, CO2在進入分子篩柱之前被反吹流入到TCD檢測器進行檢測,隨後CH4+CO+H2被分離並進入TCD進行檢測,從而得到樣品的各組分分離圖,色譜圖的數據處理由燃氣分析工作站完成,並得出各組分含量和熱值(摩爾發熱量、質量發熱量、體積發熱量、以及沃泊指數);閥切換由反控工作站完成。
