[實驗] 請問關於HPLC跑鹽類跟清洗的問題

[ Chemistry ]28 留言, 推噓總分: 0

作者: pleomax1080 - 發表於 2019/09/13 12:34(4年前)

1^F→tony15899: 你用buffer跑的過程中ACN的比例過高時鹽類就析出了09/13 12:51

2^F→tony15899: HPLC的條件在分析樣品時"洗管柱"並非必要09/13 12:52

3^F→tony15899: 如果不影響分析只要在分析完樣品再洗就好09/13 12:53

4^F→tony15899: 你的狀況要洗管柱時還要先用高水相比有機溶劑先洗掉鹽09/13 12:54

5^F→tony15899: 類才能置換成純有機相再洗09/13 12:55

6^F→tony15899: 當然那個高水相有機溶劑裡的水是純水不是用Buffer那瓶09/13 12:55

7^F→tony15899: 還有你的pump裡大概也有鹽類累積，最好用溫純水不接09/13 12:57

8^F→tony15899: 管柱洗久一點，另外如果有保護管柱的話可以換新的試試09/13 12:59

17^F→tony15899: https://reurl.cc/4gmnDR 參考PDF檔09/13 15:46

18^F→tony15899: 拉到85%ACN的溶解度都快變0了09/13 15:48

19^F→tony15899: 如果你的非高ACN條件能把雜質洗出來就延長時間09/13 15:54

20^F→tony15899: 洗不出來就直接打下一針看會不會影響09/13 15:55
