APPARATUS FOR MEASURING MOLECULAR MASS (BY MASS SPECTROMETRY) IN WHICH THE SAMPLE IS IONISED ON THE SAMPLE HOLDER AND DESORBED THEREFROM BY LASER PULSES

摘要

A probe that is removably insertable into a mass spectrometer, the probe having a sample presenting surface for presenting an analyte to an energy source that emits energy capable of desorbing/ionizing the analyte from the probe for analyte detection, wherein said surface is derivatised with a non-crystalline layer of energy absorbing molecules which are capable of absorbing said energy to facilitate the desorption of an analyte presented thereon.
