R-Biopharm Rhône has recently introduced EASI-EXTRACT® MULTI-VIT B (LGE), a new immunoaffinity column for the simultaneous analysis of multiple vitamins in a wide range of commodities. Biotin, folic acid and vitamin B12 are extracted from the sample simultaneously. The fast and convenient clean-up procedure can be performed prior to detection by HPLC or LC-MS/MS, resulting in reduced chromatography interference and lower detection limits.

EASI-EXTRACT’s procedure is based on monoclonal antibody technology, which makes the test highly specific, sensitive, rapid and simple to perform. Improved clean-up and concentration of vitamins from complex food matrices results in reduced chromatography interference and lower detection limits.

Foods like infant formula, baby food and dairy drinks are often fortified with vitamins. Since manufacturers must ensure that the labelled level of vitamin is actually present in the product, determining the vitamin content is crucial. A new immunoaffinity column makes your vitamin analysis more effective and convenient.
