ISO 22972:2004 specifies a general method for the analysis of essential oils by gas chromatography on capillary chiral columns, for the purpose of determining the specific enantiomeric excess or distribution of the chiral compounds contained in the essential oils.
Abstract
Overview
ISO 22972:2004 defines a to determine the enantiomeric excess (EE) or enantiomeric distribution of chiral constituents. It establishes the analytical principle, required apparatus and reagents, column performance criteria, calculation formulas for EE and distribution, and reporting conventions for routine chiral GC of essential oils.
