Objective:
To develop new analytical methods for water-soluble vitamins and vitamin D to replace existing, outdated methods.

Approach:
For the water-soluble vitamins, use liquid chromatography-mass spectrometry for optimized individual methods, multiple vitamin methods, and stable isotope dilution methods. For vitamin D, use liquid chromatography-mass spectrometry for an optimized individual method and a stable isotope dilution method.
