Abstract
Sub-micron chemical analysis of the surface and sub-surface of a sample material is performed at, above or under atmospheric pressure, or on for a sample material submerged in a substance. A thermal and/or topographic image of the surface of the sample material is obtained. A location for study is selected using the image. The activation device is positioned over the selected location and surface and/or sub-surface products are ablated, desorbed or decomposed from the sample material to a chemical analyzer for analysis.
