Liquid Extraction Matrix Assisted Laser Desorption Ionisation Ion Source

摘要

A Matrix Assisted Laser Desorption Ionisation (“MALDI”) ion source is disclosed comprising a first device arranged and adapted to supply a flow of liquid on to the surface of a target or a sample to be analysed so that the liquid forms a liquid junction on the surface of the target or the sample to be analysed and wherein analyte molecules to be ionised are extracted into the liquid junction, and a laser source emits a laser beam which causes analyte ions or an analyte plume to be released or desorbed from the liquid junction.
