摘要
采用GC-122气相色谱仪、PEG-20M分析柱和FID检测器,通过改变柱温、气化室温度、检测器温度3种主要影响因素,结合正交试验方案确定检测甲醇的优化条件。
In this study, GC-122 gas chromatograph, PEG-20 M analytic column, and FID detector were used for the detection of methanol in grape wine. And the optimum detection conditions were obtained through orthogonal test coupled with the change of column temperature, vaporization room temperature, and the detector temperature.
