Foreword
This standard was drafted in accordance with the rules given in GB/T 1.1-2009.
This standard replaces YC/T 242-2008 "Gas Chromatography Method for the Determination of Ethanol, 1,2-Propanediol and Glycerol Content in Cigarette Flavors", and
Compared with YC/T 242-2008, the main technical changes except for editorial changes are as follows.
---Modified the extraction solution (see 4.2, 4.7, 4.8, 4.2, 4.7, 4.8 in the.2008 edition);
---Modified the scope and preparation of the standard working solution (see 4.9, 4.9 of the.2008 edition);
---Modified the chromatographic column (see 5.2);
---Modified the sample processing conditions (see 5.4, 5.5, 6.1, 7.3.1 of the.2008 edition);
---Added a blank test (see 6.2);
---Modified the chromatographic conditions (see 6.3, 7.1 of the.2008 edition);
---Revised the calculation and expression of results (see Chapter 7, Chapter 8 of the.2008 edition).

This standard specifies the gas chromatography method for the determination of ethanol, 1,2-propanediol and glycerol in tobacco flavors.
This standard applies to the determination of ethanol, 1,2-propanediol and glycerol content in tobacco flavors.
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
A gas chromatograph equipped with a hydrogen flame ionization detector was used to determine the ethanol, 1,2-propanediol and glycerol in the diluent, and the internal standard method was used for quantification.
4 Reagents and materials
4.1 Water
It should meet the requirements of Grade 3 water in GB/T 6682.
4.2 Methanol
Chromatographically pure.
4.3 Ethanol
Purity ≥99.5%.
4.4 1,2-Propanediol
Purity ≥99.5%, should be stored in a desiccator.
4.5 Glycerol
Purity ≥99.5%, should be stored in a desiccator.
4.6 1,4-Butanediol (internal standard)
Purity ≥99.5%, should be stored in a desiccator.
