1. A system for chemical mapping comprising:
a spectroscopic imager to obtain one or more physical or chemical spatially-registered spectroscopic images of a material to be analyzed;
a sampling system to obtain a spatially-registered sample from the material to be analyzed and to transfer said material to a corresponding receptacle;
a sample transfer unit to introduce said spatially-registered sample, or a portion thereof, from the receptacle to a mass spectrometer for analysis to produce analytical mass spectral data; and
a data analysis system to collect and store the one or more physical or chemical spectroscopic images and the analytical mass spectral data wherein said data analysis system further generates co-registered information regarding the spatially-correlated spectroscopic images and the analytical mass spectral chemical data.
