更新時間:2024-04-24

填充柱進樣口進樣隔墊的更換   


工具:

尖頭鑷子         1把

實驗室手套      1副

 

材料:

581-1002   進樣隔墊   1個

 

注意事項:

1、關閉色譜儀溫控程序,降低柱箱溫度。

2、柱箱溫度將至50℃以下,保護色譜柱。

3、進樣口溫度將至100-150℃以下。

4、關閉色譜儀電源開關(不要關閉載氣、可防止汙染)。

 

步驟:

1、為了防止汙染進樣隔墊,在操作時,戴上幹淨的手套。

2、用手旋鬆進樣隔墊壓帽,取下放到一邊。

3、用鑷子取下進樣隔墊。

4、更換新的進樣隔墊,注意有孔的一麵向上。

5、安裝進樣隔墊壓帽,用手稍微擰緊即可 或者用手擰1-1.5圈 。

6、看柱前壓力的指針是否顯示正常,EPC的機型還可以在軟件裏看柱子的流量和壓力是否正常。

7、然後就可以正常工作了。
