Essential oils. Analysis by gas chromatography on chiral capillary columns. General method Ingestion-build-54371 8-chlorine substituted dibenzo-p-dioxins and dibenzofurans1 Scope This International Standard 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.
