氣相色譜譜圖分析之垂直回峰

更新時間:2021-11-17點擊次數:4427
  垂直回峰指樣品出峰的開始、結束相對基線呈垂直狀態,幾乎沒有曲線部分,而正常的出峰形狀應為高斯分布。其產生的原因及解決措施如下:
 
  1、通常是由於氣相色譜分析儀的調零不適當,91福利片导航网的零點偏離積分儀或記錄儀、色譜工作站等的工作範圍。
 
  2、一般積分儀或色譜工作站在負方向的輸入電壓範圍較小,有些積分儀或記錄儀、色譜工作站自身還具有調零功能,可以進行強製調零。
 
  3、如果91福利片导航网的零點與積分儀或記錄儀、色譜工作站自身的零點負向偏離太大,就會出現上述情形,此時請重新對91福利片导航网進行調零之後再進行分析。
