Abstract
Poly(beta-hydroxybutyrate-co-beta-hydroxyvalerate) of microbial origin has been analyzed by matrix-assisted laser desorption/ionization (MAL DI) in a time-of-flight mass spectrometer, after partial methanolysis, using two different instruments. Our results show that the mass spect ral intensities recorded in the MALDI mode correlate with previously r eported fast-atom bombardment and direct chemical ionization data. MAL DI compares favourably with these other two techniques in that it is m ore suitable to the analysis of complex mixtures and of higher molecul ar masses.
