DYNAMIC PIXEL SCANNING FOR USE WITH MALDI-MS

摘要

A method for dynamic pixel mass spectrometric imaging, or dynamic pixel imaging is disclosed. The method includes striking a sample to be scanned with a laser beam so that the laser beam releases analytes from the sample. The laser beam and the sample are then displaced relative to one another so that the laser beam substantially continuously traces a predefined path on the sample to release analytes from the sample along the predefined path. A mass analysis of the released analytes is performed.
