灵敏度直接决定着分析仪器的使用性能,从提高信号水平和降低本底噪声2个方面,对如何提高气相色谱-质谱联用仪(GC-MS)灵敏度进行了探究,并提出了相应改进方法。
Sensitivity directly determines the performance of the analytical instruments. From the aspects of improving the signal level and reducing the noise floor, how to improve the sensitivity of gas chromatography-mass spectrometry (GC-MS) has been explored, and the corresponding improvement methods have been put forward.
