Abstract
A portable Laser Plasma Spectroscopy (LPS) system and process is provided for performing in situ, near-real time, remote elemental analysis and identification of deposits or other foreign material found on surfaces of machine parts, such as turbine compressor blades or the like, wherein identification of the elemental constituents of a particular deposit is obtained without incurring significant ablative damage to the machine part substrate material underlying the deposit.
