Mass spectrometry i.e. matrix assisted laser desorption ionization-time of flight mass spectrometry, microscopy device for analyzing biological sample i.e. cell, has stack of piezoelectric units controlled for scanning sample

摘要

The device has discs (12) directly scanned over a sample, and a lens contained for focusing and for scanning a laser beam over the sample. The discs are connected with a mass spectrometer for better stability at a point, and a stack of piezoelectric units (10) is electrically controlled for scanning the sample. The sample obtains mass spectra of different regions, so that a chemical composition or a structure of the sample is out-mapped. A spatial resolution lies in x and y directions respectively between 0.1 micrometers and 100 micrometers. An independent claim is also included for a method for a mass spectrometry-microscopy.
