Flavor and Fragrance | Refractive Index Determination of Essential Oils
Refractive index measurement of essential oils is required by various monographs in international pharmacopeias. The Abbemat series from Anton Paar enables precise and repeatable measurements in accordance with ISO 280 as well as pharmacopeia standards. These instruments cover all requirements from routine quality control to high-end research applications in essential oil analysis.
Essential oils are volatile aromatic compounds extracted from plants and are used in the pharmaceutical, cosmetic, and food industries. Their refractive index is a key physical property listed in many international pharmacopeias, including the United States Pharmacopeia (USP) and the European Pharmacopoeia (Ph. Eur.). This parameter is used for identity verification, purity control, and quality assurance.
ISO 280:1998 specifies the reference method for determining the refractive index of essential oils. Anton Paar’s Abbemat refractometers, covering the 3X01, 5X01, and 7X02 series, are suitable for these measurements, providing the necessary accuracy, temperature control, and documentation capabilities.
