As it is the case for most analytical instruments, also in PTR-MS there has always been a quest for sensitivity improvement and for lowering the detection limit. However, until 2012 these improvements were limited to optimizations of the conventional setup, i.e. ion source, DC drift tube, transfer lens system, mass spectrometer (compare above). The reason for this conservative approach was that the addition of any RF ion focusing device negatively affects the well-defined … WebMALDI, de afkorting van matrix assisted laser desorption/ionisation, is een belangrijk middel voor de ionisatie van monsters die worden geanalyseerd door middel van massaspectrometrie.De afkorting MALDI wordt vaak …
