Fig 1: Chromatogram of a mixture vitamin B Standards – approx 20 ppb. B6-PM

(pyridoxamine), B1 (thiamine), B3-H (nicotinic acid), B3-N (nicotinamide), B6-PL

(pyridoxal), B6-PN (pyridoxine), B5 (pantothenic acid), B7 (biotin) and B12

(cyanocobalamin).

A blank solution containing only internal standards extracted like a sample through the

process and analyzed by LC-MS/MS did not provide any interference in analysis of

nicotinic acid and nicotinamide by the method. Peak shape of the internal standards was

good.
