Reduction of the methylene blue cation during fast atom bombardment was studied in glycerol–thioglycerol and glycerol–nitrobenzyl alcohol matrices. The relative abundances of reduced species are significantly lower in a matrix containing 0.2 m thioglycerol in glycerol than they are in pure thioglycerol. Pure 3‐nitrobenzyl alcohol or a glycerol–nitrobenzyl alcohol mixture is a less effective matrix material. These results are discussed in terms of a postulated mechanism for the formation of the reduced dye cation species.
