Foreword

GB/T 26515 "Oil Gas chromatographic General Guide" is divided into two parts. --- Part 1. the establishment of standards in gas chromatography image; --- Part 2. Oil sample image using gas chromatography. This section GB/T 26515 Part 2. This section identical with the international standard ISO 11024-2.1998 "Oil Gas chromatographic General guidelines Part 2. Oil samples The gas chromatography of the image. " This part is proposed by the China National Light Industry Council. This part of the National Fragrance Flavor and Cosmetic Standardization Technical Committee (SAC/TC257) centralized. This section is drafted.

3 Terms and Definitions

The following terms and definitions apply to this part of the GB/T 26515 of. 3.1 Representative component representativecomponents The essential oils are more or less all of the samples contained components. Example. Geranyl geraniol formate (refined) oil contains, iso menthone, citronella, geraniol and the like. 3.2 Characteristic component characteristiccomponents Representative of one or more components, for which the concentration of the oil in terms of characteristic.
