Plasma is the result of the breakdown of the atomic shell of a molecule under continual application of energy beyond the gaseous state which forms a cloud of ionized, or charged, particles. Each element of the periodic scale has a unique spectral signature, using optical emission spectroscopy (OES) to monitor the plasma and identify the component atomic elements of the plasma being sampled. Using this measurement technique would also identify additions or changes to the composition of the plasma.

Plasma measurements produce a large number of spectral peaks, to separate those peaks, Avantes’ modular design and multi-channel capability provide an excellent alternative to higher-priced traditional optical emission spectroscopy systems. With a multichannel array, each instrument is configured to cover a short wavelength range with an incredibly high resolution. The instruments are connected via fiber optics which converge into a single terminal at the collection point.

Consider one of Avantes’ two preconfigured instrument bundles designed especially for plasma and optical emission spectroscopy measurements, available in four channels or the ultra-high resolution eight channel plasma setup for desktop or rack mount installation. Or work with your qualified Avantes sales engineers to design the perfect system to meet your needs.
