4-氟-3-苯氧基苯甲醛的气相色谱分析方法

Gas chromatographic Analysis of 4-fluoro-3-phenoxy benzaldehyde

采用气相色谱法，氢火焰离子化检测器，先用6%OV-17填充柱，正二十烷为内标，气化室和检测器温度为210℃，柱温160℃，对4-氟-3-苯氧基苯甲醛进行定量测定。该方法简单，快速，准确，适用，标准偏差0.19%，变异系数0.20%，平均回收率100.0%。

A method for the determination of 4-fluoro-3-phenoxy benzaldehyde by GC was established, using 1m×2mm glass column packed with 6% OV-101/Chromsorb W HP, n-eicosane as the internal standard. The temperature of injection and detector was 210℃,d oven temperature was 160℃.The method is simple, rapid, accurate, and practical The standard deviation and variation coefficient were 0.19% and 0.20% respeetivcly, and the average recovery were 100.0%.
