Hudson Inspection Services offers on-site testing options to identify or verify material chemistry at most any stage of fabrication. We offer two methods of PMI Technologies or alloy verification to suit your engineering requirements. X-Ray Fluorescence (XRF) exposes the material to an X-Radiation beam that causes temporary excitation and emitting of secondary X-Radiation at levels characteristic for each element in the sample. XRF testing leaves no mark or alteration of the tested material, allowing for measurement non-coated finished goods. Optical Emission Spectroscopy (OES) exposes the test sample to excitation through an electrical spark between the sample and an electrode, most often in an atmosphere of high purification Argon. The spark energy results in emitted light in wavelengths and intensity characteristic to the elements in the test sample. OES analysis offers the most complete view of elements.
