This part of ISO 11024 describes general guidelines on the determination of the chromatographic profile of an

essential oil by gas chromatography on a capillary column.

The chromatographic profile is one of the specifications which enables assessment of the quality of an essential oil

in the same way as the physico-chemical characteristics. It is determined at the time of finalizing the standard on

the essential oil.

It is not a determination of the true concentration of the components, it is only an evaluation of its relative

proportions.

NOTE Refer also to ISO 11024-21) for use of chromatographic profiles of samples of essential oils.
