• Low resolution mass fragmentography is performed by monitoring simultaneously the molecular ions of the heptafluorobutyric esters of the all-trans isomer of vitamin D3 and dihydrotachysterol2, which is used as an internal standard.
• A new assay method for fatty acid synthetase using mass fragmentography is described.
• In this report the identification of compound X as 1:4-anhydroribotol by gas-liquid chromatography, mass spectrometry and mass fragmentography is described.
• A simplified assignment of absolute configuration of the amino acids in low or trace concentrations by mass fragmentography is presented.
