摘要
为使醋酸产品中丙酸含量的测定更加准确,分析过程采用气相色谱仪配置的氢火焰离子化检测器(FID),内标法测定丙酸含量。现该方法已成功推广到醋酸成品检验的实际生产中,并获得了同行业实验室的认可。
In order to increase the accuracy of the result of propionic acid content, which is produced by our factory, we use the internal reference method and Gas chromatograph with FID to analyse the acid content. The method has been spread in practical production successfully and is well recognized by the same laboratories.
