Vitamins, Co-Factors, and Enzymes

HPLC is widely used to analyze the low molecular weight, thermally labile compounds. Ideal HPLC columns for this application must possess four features: choice of bonded phase for different selectivity, high efficiency for high s/n, compatibility with different mobile phase systems and detection systems, and rugged and stable to accommodate complex, real samples. Ascentis Express columns meet these requirements.

Vitamin determination can also be performed using non-chromatographic techniques. For example, QUANTOFIX test sticks are ready-to-use, rapid (<2 minutes), semi-quantitative kits for Vitamin C (ascorbic acid). They come pre-calibrated and contain all necessary equipment and reagents. Accurate and precise, the kits include color charts that are adjusted and checked using certified standard solutions. All solutions are directly traceable to primary NIST standards.
