Inductively Coupled Plasma Spectroscopy (ICP-OES/MS), ICP Analysis Services
Evans Analytical GroupĀ® (EAG)
ICP-OES measures the light emitted at element-specific characteristic wavelengths from thermally excited analyte ions . This light emitted is separated and measured in a spectrometer, yielding an intensity measurement that can be converted to an elemental concentration by comparison with calibration standards. ICP-MS (ICP-Mass Spec) measures the masses of the element ions generated by the high temperature argon plasma. The ions created in the plasma are separated by their mass to charge ratios, enabling the identifcation and quantitation of unknown materials. ICP-MS offers extremely high sensitivity (i.e. low detection limits) for a wide range of elements
