在气谱分析中有时会遇到基线噪声变大,出现此现象直接影响到定量分析,严重时甚至使分析工作不能进行。引起噪声变大的原因很多,但可能性较大的可以从以下几个方面考虑排除。一、首先检查记录仪滑线电阻是否有灰尘或有其他脏物、可以用酒精擦洗吹干。二、注射垫用久后是否漏气或污染,可以更换新垫。 In the gas spectrum analysis, sometimes encountered by the baseline noise becomes larger, this phenomenon has a direct impact on quantitative analysis, even in severe cases can not analyze the work. There are many reasons that cause the noise to become larger, but the more likely one can be excluded from the following aspects. First, first check the recorder slip resistance whether there is dust or other dirt, you can use alcohol scrub dry. Second, the injection pad with a long time whether leakage or pollution, you can replace the new pad.
