研究了对甲苯甲醛的气相色谱分析条件。分别选用 8%OV - 2 1 0 ,1 0 %QF - 1和 8%DC - 2 0 0为固定相测定对甲基苯甲醛的含量。结果表明 :本方法快速、准确 ,标准偏差小于 0 2 %,回收率为 1 0 0 5 %～1 0 1 0 %。
The gas chromatographic conditions of p-tolualdehyde were studied. The content of p - methylbenzaldehyde was determined by using 8% OV - 210, 10% QF - 1 and 8% DC - 200 as the stationary phase respectively. The results showed that the method was rapid and accurate, the standard deviation was less than 0.2% and the recovery rate was 100% ~ 100%.
