Scientists at Sabinsa R & D continuously work on developing and validating efficient methods of analysis for the wide range of herbal extracts and nutritional supplements offered by the company. The research and development facility located near Princeton, NJ is equipped with sophisticated instrumentation including state-of-the-art High Pressure Liquid Chromatograph (HPLC), UV Spectro-photometer (UV), Atomic Absorption Spectrometer (AA), Infrared Spectrophotometer (IR), Gas Chromatograph (GC) and other relatedinstrumentation. These techniques are used to identify and quantify the active principles in various products. Product identification using Thin Layer Chromatography (TLC) techniques also forms part of the method development project.
High Pressure Liquid Chromatograph with Autosampler used for Analytical Method Development Recent methods validated include an HPLC method for the analysis of L-(+)-Selenomethionine, which measures free methionine content in commercial samples of L(+)-Selenomethionine. This method helps to distinguish between authentic samples of L(+)-Selenomethionie and samples labeled as "L(+)-Selenomethionine which are in reality physical mixtures of inorganic selenium salts and methionine.
