Specifies general guidelines on the determination of the chromatographic profile of an essential oil by gas chromatography on a capillary column. This Standard is identical with and has been reproduced from ISO 11024-1:1998.
Scope
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.
