Chemical Analysis Test Lab

Chemical analysis using Optical Emission Spectroscopy (OES) necessitates a sufficient voltage to induce an arc between a tungsten electrode and the sample to be analyzed. As a result of the burn induced on the sample, light is emitted from the sample. Each element in the sample produces a characteristic wavelength which is measured by the spectrometer.

The intensity of each wavelength is directly proportional to the concentration present. The intensities are calibrated by curves that are generated by NIST traceable or Certified Reference Materials (CRM) standards. Results are displayed in weight percent for each element chosen to be analyzed.

OES Positive Material Identification (PMI)
PMI has been developed to be a mobile application for the identification of material composition on-site.  Significant advancements have been made, and the technology as grown to include Laser Induced Breakdown Spectroscopy (LIBS) and X-ray Florescence (XRF).  While they each have their benefits, neither is more accurate than Optical Emission Spectroscopy (OES) at performing highly accurate readings on steel materials for carbon and X-Factor (X-Bar) calculations for  elements such as Phosphorus, Antimony, Tin, & Arsenic on P11 & P22 CrMo pipe and fittings.  However, it takes a more sophisticated technician to operate this equipment effectively.  Quality Testing utilizes the best-in-class OES-PMI analyzers from Belec and Hitachi Smart to and highly trained technicians to deliver reliable full chemistry data for your material identification requirements.
