氣相色譜檢測器的分類

更新時間:2021-11-17點擊次數:3681
  1、根據樣品是否被破壞
 
  ①破壞性檢測器:FID、NPD、FPD、MSD、AED
 
  ②非破壞性檢測器:TCD、PID、ECD、IRD
 
  2、根據相應值與時間的關係
 
  積分型檢測器、微分型檢測器。目前流行的檢測器都是微分型檢測器。
 
  3、根據對被檢測物質響應情況的不同
 
  ①通用型檢測器,如:TCD、FID、PID
 
  ②選擇性檢測器,如:FPD、ECD、NPD
 
  4、根據檢測原理的不同
 
  ①濃度型檢測器:測量的是載氣中某組分濃度瞬間的變化,即檢測器的響應值和組分的濃度成正比。如熱導
 
  檢測器和電子捕獲檢測器。
 
  ②質量型檢測器:測量的是載氣中某組分單位時間內進入檢測器的含量變化,即檢測器的響應值和單位時間
 
  內進入檢測器某組分的量成正比。如火焰離子化檢測器和火焰光度檢測器等。
 
  凡非破壞性檢測器,均為濃度性檢測器。
