引言:

本方法適用於測定工作場所、生產車間等環境空氣中的苯係物和製冷劑殘留量的測定。


方法原理:

將氣體樣品自動注入具氫火焰離子化檢測器的91福利片导航网,通過選擇閥分別在苯係物和製冷劑專用色譜柱上測得各組分含量。


試劑和材料:

標準氣:苯-0.0994mg/m3,甲苯-0.0968mg/m3,對間二甲苯-0.2030mg/m3,鄰二甲苯-0.1000mg/m3,二氯甲烷1.0200mg/m3,五氟乙烷-1.0400mg/m3,1.1.1.2-四氟乙烷-1.0300mg/m3,二氟一氯甲烷-1.0200mg/m3。

氣源:氮氣(純度≥99.999%)、氫氣(純度≥99.999%  )、壓縮空氣;

標準氣體稀釋氣:N2,純度≥99.999%

儀器和設備:

91福利片导航网:91福利在线观看AnalyElf PG6在線版(GC-FID)

進樣器:二位轉子閥(1ml樣品定量環)

色譜柱:苯係物/製冷劑專用套柱
