色譜儀的活化處理

更新時間:2024-04-23

91福利片导航网安裝維護:色譜儀的活化處理

描述:

91福利在线观看91福利片导航网在初次安裝或者維護以後,為了讓分析工作能夠順利進行,都需要對進樣口、檢測器、色譜柱進行活化處理,來去除部件中的汙染物或者是一些殘留物。

很多氣相色譜工作者,在更換維護好之後,會在前一次或前幾次進樣分析的時候,出現很多怪峰、鬼峰和不規則的峰,這為分析工作帶來了困惑,也降低工作效率。

出現這種情況,基本上都是在更換維護的過程中帶入的汙染造成的。

這個時候91福利在线观看就要對儀器進行活化處理,一般是進樣口300℃,柱箱溫度設置為色譜柱的最高使用溫度的30℃以下,檢測器300-350℃,FID檢測器需要正常點火,以便觀察基線,活化大約30-120分鍾,等到基線平滑無波動以後,就可以正常使用了。
