Extracts and concentrates from the production process of reconstituted tobacco Determination of solid content

1 Scope

This standard specifies the method for determination of solid content in extracts and concentrates during the production process of reconstituted tobacco. This standard applies to the determination of solid content in extracts and concentrates during the production process of reconstituted tobacco, including total solids, soluble solids, and insoluble solids.

2 Normative references

The following documents are indispensable for the application of this document. For dated reference documents, only the dated version applies to this article Pieces. For undated references, the latest version (including all amendments) applies to this document. GB/T 6682 Analytical laboratory water specifications and test methods

3 Principle

Take a certain amount of extract or concentrate sample from the production process of reconstituted tobacco and pretreat it with ethanol containing internal standard substance (isopropanol). The water content of the obtained treated liquid is determined by gas chromatography, and the water content is deducted to be the solid content of the extract or concentrate. Which can Water-soluble substances are soluble solids, water-insoluble substances are insoluble solids, and the sum of soluble solids and insoluble solids is the total solids.

4 reagent

4.1 The water should meet the requirements of Grade 1 water in GB/T 6682. 4.2 Anhydrous ethanol, the moisture content should be less than 1.0mg/mL. 4.3 Internal standard, isopropanol, with a purity of not less than 99%. 4.4 Pretreatment reagent Take 12.5mL of the internal standard substance (4.3) and add it to 1L of absolute ethanol (4.2) and mix well. The pretreatment reagent should be shaken continuously before use to make the moisture even. Pretreatment reagents and test samples used in the preparation of standard working solutions The pretreatment reagent should be the same batch. 4.5 Standard working solution Accurately weigh a certain amount of water (4.1), accurate to 0.0001g, in a 50mL conical flask with stopper, add 50mL of pretreatment reagent (4.4), Mix well to obtain a series of standard working solutions. The standard working solution should be prepared for immediate use. The quality of the recommended series of standard working solutions is shown in Table 1.
