本文主要就气相色谱-质谱联用仪在校准时所长出现的信噪比低、谱库检索相似性较差、信噪比不足,以及还有可能会出现的相关检索错误等问题展开了具体的分析。进而针对以上问题就检测仪器的真空度处理、调谐参数设置、信噪比计算以及谱库检索所应当加强注意的内容等多个方面指出了一些具体的处理措施,希望能够给予相关的气相色谱-质谱联用仪校准工作一些可供参考的内容。
In this paper, the issues of low signal-to-noise ratio, poor library search similarity, insufficient signal-to-noise ratio and related retrieval errors that may arise when using GC-MS are discussed Analysis. In order to solve the above problems, some specific measures are pointed out, such as the vacuum degree of the testing instrument, the setting of tuning parameters, the calculation of the signal to noise ratio and the contents of the library search. Some specific measures are pointed out, Mass spectrometer calibration work for some reference content.
