Essential oils. Analysis by gas chromatography on capillary column. General method.

La présente norme fait partie d'un ensemble de normes pour le contrôle de la qualité des huiles essentielles et matières utilisées dans l'industrie de la parfumerie et des arômes. Les propriétés parfumantes, aromatisantes, thérapeutiques et toxicologiques d'une huile essentielle sont étroitement liées à sa composition chimique. La recherche de la conformité de cette composition chimique à celle d'une huile essentielle de référence est la base du contrôle de la qualité. L'analyse par chromatographie permet l'obtention, sous la forme d'un chromatogramme, d'un reflet de la composition chimique d'une huile essentielle et permet l'évaluation précise de la concentration des constituants considérés comme importants. Cette norme traite plus particulièrement des principes généraux d'analyse par chromatographie en phase gazeuse sur colonne capillaire, auxquels se réfèrent certaines des méthodes particulières.
