First Claim
1. A method for performing an assay of at least one target vitamin in an oral care product, said method comprising:
- a) preparing a first analyte comprising a standard solution of the at least one target vitamin to be assayed;
b) preparing a second analyte comprising a sample solution derived from the oral care product containing the at least one target vitamin;
c) preparing a third analyte comprising a placebo solution derived from the oral care product, which does not contain the at least one target vitamin;
d) chromatographically analyzing and providing a chromatogram for each said analyte;
e) comparing the chromatograms of the first and second analytes to determine the amount of the at least one target vitamin in the sample solution; and
