摘要
介绍了一种三重四级杆气相色谱-质谱联用仪检出限的评定方法。建立了检出限的数学计算模型,对检出限的评定方法进行了实验验证。实验结果表明,该方法评定的检出限可以作为评估三重四级杆气相色谱-质谱联用仪灵敏度的性能指标。
An evaluation method for the detection limit of triple quadrupole gas chromatography-mass spectrometrys is introduced in the paper. The mathematical model of the detection limit is established, and the evaluation method is veriifed by experiments. The experimental results show that the detection limit evaluated with the method can be used as a performance index to evaluate the sensitivity of triple quadrupole gas chromatography-mass spectrometrys.
