The detection and characterization of trace levels of organic surface contaminants has presented a most difficult problem to the materials analyst. In recent years plasma chromatography/mass spectroscopy (PC/MS) and atmospheric pressure ionization mass spectroscopy (APIMS) have been demonstrated as techniques which can detect subpicogram quantities of organic compounds. However, no means of area resolution is available with these techniques. More recently a system of the Instruments SA, Inc., called the Microprobe Mole, which is a laser Raman microprobe spectrometer, has been developed to analyze both organic and inorganic compounds on a micron scale.
