摘要
建立了用气相色谱法,毛细管色谱柱,氢火焰离子化检测器,分析乙醛和三聚乙醛含量的方法。检测条件为:汽化温度160℃,柱温110℃,氢焰温度160℃,载气(N2)压力控制在0.06 MPa,采用校正面积归一化法定量,测量了在各种浓度下乙醛相对于三聚乙醛的校正因子为1.17。
The method of using the gas chromatograph, capillary chromatographic column, hydrogen flame detection for analyzing content of Acetaldehyde and Paraldehyde was established. Testing conditions is boiloff temperature 160 ℃, column temperature 110 ℃, hydrogen flame temperature 160 ℃, control pressure of carrier gas （N2） 0.06 MPa, correction factor relatively of acetaldehyde and paraldehyde in different content of acetaldehyde and paraldehyde was measured by rectify area normalization method, and the value is 1.17.
