Phyto Primary Reference Standards and Extracts (Secondary Reference Standards)

For the Analysis of Herbal Medicinal Products

In collaboration with HWI ANALYTIK GmbH - a company with almost 20 years of experience in the analysis of pharmaceutical products - Sigma-Aldrich provides a new class of primary reference standards for use in quality control, in-process control and stability testing of herbal medicinal products.

These standards are produced and qualified by HWI ANALYTIK and are exclusively distributed by Sigma-Aldrich. The novel certification concept of these reference standards is based on the quantitative NMR technique (qNMR) for content assignment*. The application of qNMR, a relative primary method of measurement, is advantageous compared to the usual mass balance approach using two chromatographic methods, Karl Fischer titration for water determination, residue on ignition for inorganic impurities and residual solvent determination, due to higher reliability of the certified content value.
The analytical report delivered with these products contains two identity proofs, the content by qNMR and the chromatographic purity.

Comprehensive documentation on further parameters, detailed method descriptions and validation data can be ordered directly from HWI ANALYTIK.

(*exception 00320188 (-)-α-Bisabolol: content is determined by the 100% minus impurities approach)
