Testing reports values for vitamin D3 (cholecalciferol). Following a saponification procedure to remove fat from the sample, the mixture is taken for liquid-liquid extraction into petroleum ether. The extract is then filtered and evaporated to dryness. The analyte is reconstituted in methanol and quantitated using reverse phase HPLC with a triple-quad mass spectrometer.
