Abstract
A mass spectrometry method for analysing the presence or absence of at least one target analyte in a complex sample is provided. The method uses a sample carrier suitable for mass spectrometry with a pre-applied microcrystalline MALDI matrix spot which is at least partially encompassed by a hydrophobic region. A complex sample is applied such that it becomes located on the microcrystalline MALDI matrix spot. The sample is washed on the microcrystalline MALDI matrix spot and then analyzed for the presence or absence of at least one target analyte via mass spectrometry. The method is in particular suitable for quantitatively analysing target analytes such as hepcidin and other peptides, drug compounds and metabolites in body fluids.
