本标准提供了有关分析的所有经常性参数、仪器、产品、方法和公式的详细信息。该方法包括在直径小但长度大的色谱柱上分析少量精油，色谱柱内壁之前已直接涂有指定的固定相或浸渍支架。如果需要，根据保留指数确定不同的成分。通过测量峰面积对特定成分进行定量测定。

The Standard gives detailed information on all recurrent parameters, apparatus, products, methods and formulae for the analysis. The method consists in analyzing a small quantity of essential oil on a column of small diameter but great length, the inside wall of the column having been previously coated either directly with a specified stationary phase or with an impregnated support. If required different constituents are identified from their retention indexes. Quantitative determination of specific constituents is carried out by measurement of peak areas.
