Principle of the method:
Determination Method for Vitamin D derivatized with 4-phenyl-1,2,4-triazoline-3,5-dione(PTAD) in Milk Powder by UHPLC-MS/MS
Test sa ples are saponified, extracted, and the solvent evaporated. Vitamin D is derivatized with 4-phenyl-1,2,4-triazoline-3,5-dione, and then determined by UHP
