About this document
Methods for Analyzing Vitamin B12 by Vikas Goyal is a document available to read on EtoBox.
1) The document describes two new analytical methods - a UV/VIS spectrophotometric method and an HPLC method with UV/VIS detection - for determining the concentration of vitamin B12 in various pharmaceutical dosage forms. 2) The UV/VIS spectrophotometric method measures absorbance at 550 nm and is low-cost with acceptable specificity, but has relatively low sensitivity for complex samples. 3) The HPLC method uses a C18 column, mobile phase of acetonitrile and potassium phosphate buffer at pH 2.5, and de
