Dual interior labels gas chromatography test method for determining contents of various organic ingredients in cellulose acetate fiber filter stick

The invention discloses a dual interior labels gas chromatography test method for determining contents of various organic ingredients in a cellulose acetate fiber filter stick. Interior labels adoptedcomprise n-heptadecane and n-propyl benzoate and are respectively used for determining contents of triacetin, menthyl lactate and menthol carboxamide with higher contents and contents of 1, 2-propylene glycol and menthone with lower contents. According to the method, the additive amounts of the selected interior labels differ widely, the interior labels can be respectively used for measuring contents of five organic substances with different contents, different structures or different natures, and the method has the advantages of being less in mutual interference, high in measurement accuracy, small in error and short in time. 本发明公开了种测定醋酸纤维滤棒中多种有机成分含量的双内标气相色谱测试法，采用的内标物种是正十七烷，第二种是苯甲酸正丙酯，分别用于测定含量较大的三乙酸甘油酯、乳酸薄荷酯、薄荷酰胺的含量以及含量较小的1,2-丙二醇、薄荷酮的含量。本发明选用的内标物添加量差异大，可以分别测量不同含量、不同结构或不同性质的五种有机物质的含量，相互干扰少，测量精度高，误差小，时间短。
