Analysis of pentoxifylline using matrix-assisted laser/desorption/ionsation, mass spectrometry
Abstract
The possibility of pentoxifylline analysis using matrix-assisted laser/desorption/ionsation mass
spectrometry (MALDI MS) was investigated. Influence of matrix nature, sample preparation method and
laser settings on mass spectrocoric characteristics were studied. It was shown that MALDI MS allows to
analyze pentoxifylline at 8*10-15 level. Fragmentation pathways of protonated molecular ions were
studied using MALDI mass-spectrometry. The results were compared with respective literature data
received with electrospray ionisation
