In Purification columns, Vitamins

Scientists from Sun Yat-Sen University (Guangzhou, China) have developed an improved procedure for water-soluble multi-vitamin analysis. Heng Zhang et al. in the June 2014 issue of Food Chemistry report a novel extraction buffer which enables efficient simultaneous co-extraction of vitamin B12, folic acid and biotin from infant formula.

These authors employed this buffer in conjunction with R Biopharm VitaFast® test kits obtaining impressive performance in terms of quantifying these vitamins compared with conventional microbiological analysis.  A strong case is made for moving towards multi-vitamin analysis, which is consistent with the strategy being developed by R Biopharm Rhône with the development of a new multi-vitamin immunoaffinity column for vitamin B12, folic acid and biotin.  The R Biopharm team will shortly be publishing the results of their single laboratory validation of this novel immunoaffinity column for multi-vitamin analysis.
