Common Problems and the Solutions in Calibration of GC–MS

气相色谱–质谱联用仪校准常见问题有分辨率偏低、信噪比低及谱库检索相似度偏低或者检索错误等。从仪器真空度的检查处理、调谐参数设置、信噪比计算方法、谱库检索注意事项等方面提出了气相色谱–质谱联用仪校准问题的解决方法,为台式气相色谱–质谱联用仪的校准工作提供参考。

Common problems in calibration for gas chromatography-mass spectrometry（GS-MS） include low resolution, low signal-noise ratio, and low similarity in retrieval of library （or retrieval error）. As references for calibration of GC-MS, it introduced solutions of calibration of GC-MS from some aspects, such as examination of the vacuity, adjustment of the parameters, calculation of the signal-noise ratio, precautions in retrieval of library.
