ISO 11024-1:1998

Essential oils — General guidance on chromatographic profiles — Part 1: Preparation of chromatographic profiles for presentation in standards

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.
