Imaging mass spectrometer and a method of mass spectrometry

摘要

An imaging mass spectrometer comprising an energy source adapted to substantially simultaneously provide energy to multiple spots on a sample to produce ions from the sample by a desorption process; and an analyzer adapted to detect the arrival time and spot origin of ions resulting from said desorption process.

1. An imaging mass spectrometer comprising:
an energy source adapted to substantially simultaneously provide focused beams of energy to multiple spots on a sample to produce ions from the sample by a desorption process; an analyser adapted to detect the arrival time and spot origin of ions resulting from said desorption process; and a sample plate for receiving the sample, wherein the energy source is adapted to provide energy on the sample through the sample plate at an angle substantially perpendicular to the surface of the sample at each of the respective spots.
