This imaging mass spectrometer has a spatial resolving power at the specimen of (84±35)μm with a mass resolution of 45 and locates atoms or organic compounds on a surface area up to~2 cm 2 . ...
Most mass spectrometric imagers acquire high mass resolution spectra spot-by-spot and thereby scan the object's surface. Thus, imaging is slow and image reconstruction remains cumbersome. ...
The authors are grateful to Professor Rüdiger Brenn for providing main parts of the time of flight spectrometer. The help of Dr. ...
