Abstract

Negative ion fast atom bombardment mass spectrometry employing a hexamethylphosphoric triamide-glycerol (1 : 1, v/v) mixture as a matrix has been found to facilitate the molecular weight determination of hydrolyzable tannins in their free forms, as well as the detection of diagnostic fragment ions.
