Pyrolysis-direct chemical ionization mass spectrometry experiments were carried out under positive and negative ionization conditions on the polysaccharides amylose and dextran, (1 → 4)-α-glucan and (1 → 6)-α-glucan. Ions were observed in the higher mass range, corresponding to hexose fragments up to four hexose units. Some of these specific fragments were investigated by tandem mass spectrometry. The applicability of positive and negative ionization conditions with respect to the specific detection of compounds in complex pyrolysates from a Penicillium italicum strain, cultured with and without the fungicide imazilil, were compared. Different constituents of the complex pyrolysates were more or less emphasised by the ionization conditions applied. Variation of these conditions provided information on both pyrolytic and ion chemistry processes. © 1989.
