目的:对七氟烷建立气相色谱法定量分析。方法:氢火焰离子化检测器-气相色谱法定量样品中七氟烷。结果:在浓度50μg/ml~800μg/ml范围内呈良好的线性关系,线性回归方程为Y=2.2293X+0.0277,相关系数r2=0.9999,信噪比为3时,得七氟烷最低检出限为0.50μg/ml,回收率大于98%,日内和日间RSD都小于1%。结论:建立氢火焰离子化检测器-气相色谱法检测分析七氟烷含量,选择性好,分离效果好,定量分析结果准确,可用于七氟烷的测定。
Objective: To establish a gas chromatographic quantitative analysis of sevoflurane. Methods: Sevoflurane was quantified by flame ionization detector-gas chromatography. Results: The linear regression equation was Y = 2.2293X + 0.0277 with a correlation coefficient of r2 = 0.9999 at a concentration of 50μg / ml ~ 800μg / ml. The lowest sevoflurane was obtained when the signal to noise ratio was 3 The limit was 0.50 μg / ml, the recovery was greater than 98%, and the intra-day and inter-day RSDs were less than 1%. Conclusion: The determination of sevoflurane content by gas chromatography with hydrogen flame ionization detector - gas chromatography has good selectivity and separation effect. The quantitative analysis results are accurate and can be used for the determination of sevoflurane.
