Abstract
Abstract
Vitamin D is a fat-soluble vitamin with great nutritional interest. An HPLC/MS/MS method was developed to measure vitamin D with atmospheric pressure chemical ionization. Under the experimental parameters used, the LOQ was 0.018 IU/g or 0.45 ng/g, which greatly enhances the capability of measurement of vitamin D at low levels in foods and supplements. This method was validated with spike recovery of 100 15 and the RSD of less than 10 for most sample matrixes, including infant formula, cheese, cereal and cerealbased foods, multivitamin supplements, and pet foods. The results for vitamin D were compared with those obtained by other methods.
