Optical Emissions Spectroscopy (OES) Advances the Industrial Automation Plants
Published by : Industrial Automation
Optical emission spectroscopy (OES) is an analytical concept primarily used in the industrial automation plants for the identification of elements. OES’s power is used as an analytical technique for elemental identification, which primarily enables its growth in the industrial automation plants. It is widely used in the manufacturing industries, especially in the metal-production industries.
OES is composed of three main components i.e. excitation source, diffraction grating, and detector. The excitation source primarily energizes the electrons to move at the higher energy levels from which they subsequently relax and emit light. These emitted wavelengths of light are further detecting to specify characteristics of wavelengths through emitting atom. While the diffraction grating is used to splits the emitted different wavelengths of light. This results in the identification and record position of various components or spectral lines that the emitted light through the sensitive detector.
How efficient is using Optical Emission Spectrometers for Industrial Automation
• OES enables relative simplicity, which makes it ideal for integration into automated industrial plants. It is used to quality control in wafer manufacturing
• Plasma deposition based on OES is commonly used to create layers of chemical species onto a substrate to treat all wafers in a similar pattern
• In the industrial automation fabrication process, the data output of the OES can be categorized as part of a feedback system with the manufacturing process
• OES are primarily integrated to monitor the conditions in the plasma and the relative ratios of different chemical species of the chemical reaction, along with the endpoint for the processing
• Deposition processes are totally based on the automation algorithm of data analysis and element identification. The atomic layer deposition is used for the creation of ultra-high quality thin films.
• Automated OES is widely adopted in the metallurgy industries, as it assists in the identification of many elements such as carbon and phosphorous
• Automated OES is also used to carry out impurity testing as part of quality control. It further uses investigative work looking at the presence of impurities and their relative concentrations in the materials or elements
In the current scenario, a wide number of commercial optical emission spectrometers are available in the global market that is integrated in robot-based automatic samplers for the application of analysis and identification. This makes it useful process integration such as metal identification and scrap sorting.
It is also stated that automation reduces processing blocks and enhance production efficiency with the advantage of complete reliability and reproducibility in the processing and analysis of samples. Moreover, the automated OES are significantly reduced cost and overall time for testing as well as the identification process of elements or materials often accounts for a large proportion of manufacturing costs.
