  • Using emission spectroscopy to perform impurity analyses in UHP gases
    , but of equal importance was the use of a new technique: emission spectroscopy. When excited in an electric discharge, the gases dissipated some of the energy as electromagnetic radiation at wavelengths that were specific to each gas. The spectral lines were intense enough to be easily observable
  • Overview of Rotating Disc Electrode (RDE) Optical Emission Spectroscopy for In-Service Oil Analysis
    The basis of modern oil analysis is the use of optical emission spectroscopy (OES) to measure the ppm (parts per million) levels of wear metals, contaminants and additives in oil samples. Whatever else an oil lab may measure, a multi-elemental analysis is the core of in-service oil analysis
  • Elemental Analysis - New Capabilities for Spectroil Optial Emission Spectrometer
    Wear debris analysis is an important part of any oil analysis program. The Spectroil RDE spectrometer measures trace quantities of elements dissolved or suspended as fine particles in lubricants using the time-tested technology of rotating disc electrode. (RDE) atomic emission spectroscopy
  • Detection of hydrocarbon radicals during plasma etching
    Optical emission spectroscopy is used to study and monitor the plasma etching of. hydrogenated amorphous carbon (a-C:H) thin films.
  • A Spectroscopy Guide for PAT
    of fluorescing is "multidirectional, " the detectors are placed perpendicular to the incident light. Thus, unlike UV/Vis, small absorbances (followed by emission) and not the total ouput of the light source are seen against a "dark " background. This allows for detection of trace amounts of analyte
  • Atmospheric Plasma Analysis by Molecular Beam Mass Spectrometry (.pdf)
    The use of atmospheric plasmas is growing in interest due to their advantage in processing materials, mainly organic, which are not suitable for high vacuum. Such discharges are commonly studied by optical emission spectroscopy but, to understand the surface properties of the treated material
  • Detrimental Element Analysis of Non-Metallic Materials Used in Nuclear Reactors
    for halogens, sulfur, and low-melting point metals by ASTM D129, E144 and D3761, using oxygen bomb or water leaching preparation with ion chromatography (IC) and inductively-coupled plasma (ICP) optical emission spectroscopy (OES or AES) is described. Some independent testing laboratories are approved
  • X-MET8000 Series For Rapid Flow
    of these elements are below a given level (e.g. Cr < 0.05%), FAC will occur significantly faster. This is why it is essential to monitor the contents of these alloying elements. Traditionally, optical emission spectroscopy (OES) has been used for this analysis. Recent developments in X-ray fluorescence
