摘要
采用静态顶空气相色谱法测定定型发胶中甲醇含量,确定了最佳平衡温度平衡时间、盐析剂、及色谱操作条件等,标准偏差为0.190～0.409,相对标准偏差为0.95％～2.20％,平均回收率为96.8％。
The method of determination of methanol in styling spray with headspace gas chro-matography was established. The conditions used are GDX-102 on 80-100 mesh packed in a 2m mm i.d. column operated at 150癈. The temperature of both FID detector and injector is 190癈. SD was found 0.190-0.409, and RSD 0.95-2.20%. The average recovery was 96.8%.
