Essential oils

These essential oil reference materials are manufactured by HWI ANALYTIK and are designed to serve as a reference for the analysis and study of essential oils in pharma (herbal medicinal products), F&B or in the cosmetics industry. For several characteristic components of each oil, the identity is confirmed and the peaks in the chromatogram are assigned by comparison to analytical standards. In addition, one or two key components are quantified and traceable to the corresponding HWI primary pharmaceutical standard (whose content is determined by quantitative NMR).

Packaging and Documentation
The essential oil reference materials are sold in units of 1mL each. The product is accompanied by a certificate containing information about the tested identity markers as well as giving the quantitative value for the quantified component as a mass fraction (mg/g). In addition, a leaflet is delivered along with the product, containing further details such as the chromatographic method and chromatograms of the oils including peak assignment and a chromatogram of the standard solution used for quantification of the marker.
