MCLinc’s experienced professional staff, working with a unique and powerful collection of materials characterization equipment, has successfully identified a variety of unknown substances. Advanced instrumentation includes optical and electron microscopes, x-ray diffraction, x-ray fluorescence, infrared spectroscopy, gas chromatography, ICP for trace metals analysis, liquid scintillation and gas-proportional counters for radiochemical analyses, ion chromatography, well-equipped sample preparation and wet chemistry analysis laboratories, and equipment for explosivity testing. This fusion of instrumental, laboratory and personnel resources provides a dedicated technical services group capable of identifying unknowns that originate from a number of sources. For the project illustrated, MCLinc identified the gas that had been contained in a cylinder prior to rupture of the cylinder. Residues found inside the cylinder provided the primary evidence used for identification. Corrosion products on metals surfaces were examined to establish the approximate age of the rupture. |
