Determination of Biotin by High-Performance Liquid Chromatography in Infant Formula, Medical Nutritional Products, and Vitamin Premixes
A solid-phase extraction sample preparation procedure was developed for use with a high-performance liquid chromatography (HPLC) method for biotin analysis. The HPLC method used a reversed-phase C18 column; chromatography run time was 8.5 min. After eluting from the column, biotin went through postcolumn reaction to form a conjugate with streptavidinfluorescein isothiocyanate, which was then detected by a fluorescence detector. This method was tested with infant formula, medical nutritional products, and vitamin premix samples.
