Atomic and Optical Emission Spectrometers (OES)

Optical Emission Spectroscopy (OES) is a technique used to determine the elemental composition of a wide range of metals. All OES analyzers contain the same main parts. An electrical source excites atoms in a sample so they discharge a distinctive light. A diffraction grating then separates the emitted light into wavelengths of light that are specific to individual elements, and a corresponding detector gauges the power of light for each wavelength. The intensity assessed is proportional to the concentration offset element in the sample. The computer system acquires the measured strengths and processes this information using a predetermined calibration to output elemental amounts. The user interface ensures a relative ease of use and clearly presents test results.
