Traditionally x-ray spectrometers have been designed to analyze perfectly prepared specimens that are flat and highly polished such as 32mm discs. Certainly the best analytical results are obtained on such samples, however in an industrial laboratory it is also neccessary to obtain statistically valid results on samples that are less than ideal in size and geometry. The problem at the TRIDENT Refit Facility is to analyze large metal parts such as pump casings, valve bodys, flanges, and finished piping sections that are going into the repair of TRIDENT class submarines. Energy dispersive X-ray techniques have long been recognized as fast and non-destructive and are therefore ideally suited to the analysis of these finished metal parts.
