Analysis of Organic Surface Contaminants by Plasma Chromatography - Mass Spectroscopy and Raman Microprobe Techniques

A major problem in the analysis of surface contaminants is the identification and characterization of organics, especially of small areas. The frequently-used surface analytical techniques provide elemental information which is insufficient for organic analysis. Plasma chromotography-mass spectroscopy and the laser Raman microprobe technique are useful in characterizing organic surface contaminants. Both techniques are described and examples of application of the techniques are given.
