GLC Analysis of Menadione Bisulfite Addition Compounds by On-Column Pyrolysis to Menadione

The GC determination of the on-column pyrolysis product of menadione bisulfite addition compounds as menadione is described. Differential thermal analysis, mass spectroscopy, and GC retention times conclusively prove the feasibility of on-column pyrolysis of menadione bisulfite addition compounds to...
