## Abstract Electrospray ionization mass spectrometry (ESIβMS) was successfully applied to the structural analysis of lignin. The structure of oligomers fractionated from Eucalyptus globulus dioxane lignin was elucidated using tandem mass spectrometry, and the information on fragmentation patterns
The mass spectrometry (MS) behaviour of ten commercially available penicillins has been studied by means of electrospray and multiple-stage MS/MS experiments performed using an ion trap instrument. For all the examined compounds negative ions are produced under ESI conditions, with a yield two or th
