Abstract
A model for plasma formation in the plume of desorbed material in UV l aser MALDI (matrix assisted laser desorption/ionisation) is proposed b ased on thermal ionisation of the photoexcited matrix vapour. Signific ant ion yields are obtained at modest plume temperatures and the predi cted ion yield-fluence scaling is in considerably better agreement wit h experiments than results obtained using a photoionisation model.
