Embodiment Construction

[0039] Such as figure 1 The shown double internal standard gas chromatography test method for determining the content of various organic components in cellulose acetate filter rods uses two internal standards for gas chromatography testing, one of which is n-heptadecane, which is used for the determination of three The content of glyceryl acetate, menthyl lactate, and menthyl amide; the second internal standard used, n-propyl benzoate, is used to determine the content of 1,2-propanediol and menthone. The respective contents of triacetin, menthyl lactate, and menthyl amide are of the same order of magnitude, and the usage amount of n-heptadecane is also of the same order of magnitude as these three contents; the respective contents of 1,2-propanediol and menthone are of the same order of magnitude. An order of magnitude, the usage amount of n-propyl benzoate is also the same order of magnitude as these two kinds; the former order of magnitude is 1-2 orders of magnitude greater ...

Abstract

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.

Description

technical field [0001] The invention relates to a technique for measuring the content of chemical components in fiber materials. Background technique [0002] Acetate fibers need to add more organic reagents during the synthesis and spinning production process, and also need to add binders, plasticizers, special functional reagents, etc. when manufacturing cigarette filter rods, so the filter rods have more properties. chemical composition with large differences. The content of these components needs to be accurately measured and controlled in order to produce qualified finished filter rods. [0003] The invention with the application number of 2010100420620 discloses a method for detecting the accuracy of flavoring amount added to cigarette filter sticks, (1) adding spices and markers to cigarette filter sticks in a certain proportion during production; (2) extracting cigarette tip sticks at equal times As a test sample; (3) with absolute ethanol as a solvent, 1,4-butaned...
