I. 常见问题
基线噪音
可能的原因:
1.流动池脏
2.检测器灯有问题
3.如果是周期性的,则起源于泵的脉冲
4.温度对检测器的影响
5.气泡经过检测器

ng, and high pressure operation of the column. Degassing solvents preferable with an in line vacuum is highly recommended. Also, using a high pressure flow cell with post cell flow restriction will help to keep any residual gas in solution so there is no out gassing in the cell. This can be accomplished with a small piece of small ID tubing.

基线漂移
可能的原因:
· 梯度洗脱
· 温度不稳定 (示差检测器)
· 流动相中有污染物
· 柱中的流动相没有平衡
· 体系中有污染物流出
