INDUCTIVELY COUPLED PLASMA (ICP) Testing

ELEMENTAL ANALYSIS OF ALLOYS, POLYMERS AND PLASTICS

ICP-2

Inductively Coupled Plasma – Atomic Emission Spectroscopy uses quantitative measurement of the optical emission from excited atoms to determine analyte concentration. A liquid sample is converted to an aerosol and then atomized by a plasma which provides sufficient energy to promote the electrons of atoms into high energy levels. As the electrons decay back to their ground energy state light is emitted.

Each element emits light at specific wavelengths and is therefore identifiable. The light is dispersed into its spectral components and measured on a SCD (Segmented Charged-Coupled Device) detector. The intensity of the light, measured at various wavelengths, is proportional to the concentration of the element in the sample.

The concentrations are calculated from daily calibration curves suitable to the alloy and are shown directly as percent concentration of the element.
