ICP Operations The ICP (Inductively Coupled Plasma)
With ICP emission, elemental concentrations are determined by measuring light intensities at discrete wavelengths. Because the ICP is a very high temperature source, it emits many thousands of wavelengths - a "complex spectrum". The job of the spectrometer's optics is to make sense of this information and the best way to do this is to use an Echelle optical system with a large output format. The ICP's Echelle optics disperse the spectrum, widely separating the wavelengths thereby minimizing interferences and the need for interelement corrections. The design also improves resolution - the ability of a spectrometer to distinguish between two closely spaced wavelengths - without reducing the amount of light that gets to the detector.Importance of ICP Analysis
