Product Description
An portable Optical Emission Spectrometer (OES) is a scientific instrument used to analyze the chemical composition of materials, primarily metals. It works based on the principle of atomic emission spectroscopy. When a material is excited with energy (typically in the form of a high-energy plasma), the atoms in the material emit light at characteristic wavelengths. By measuring the intensity of this emitted light at specific wavelengths, the elemental composition of the material can be determined.
The basic components of an OES typically include:
1. Excitation Source: This can be a high-energy arc or spark generated between an electrode and the sample, or it could be a laser in the case of laser-induced breakdown spectroscopy (LIBS).
2. Optical System: This system collects the emitted light from the excited atoms and directs it towards the spectrometer.
3. Spectrometer: The emitted light is dispersed into its component wavelengths by a diffraction grating or prism. The spectrometer then measures the intensity of the light at specific wavelengths.
4. Detector: A detector, such as a photomultiplier tube (PMT) or charge-coupled device (CCD), measures the intensity of the light at each wavelength.
5. Data Analysis Software: Specialized software is used to analyze the data collected by the detector and determine the elemental composition of the sample.
