CHEMICAL ANALYSIS (PMI = POSITIVE MATERIAL IDENTIFICATION)

Chemical analysis (PMI = Positive Material Identification) of metal alloys is performed on bulk material (fittings, pipes, valves, flanges) in order to verify that the material complies with the manufacturer's declaration. The analysers used employ the analytical technique of X-ray fluorescence through radioscopic excitation to verify the quality or type of alloy and the quantitative analysis of the chemical composition of many ferrous materials as well as nickel and cobalt alloys.
