Inductively Coupled Plasma Optical Emission Spectrometer (ICP-OES)

Excites atoms in an argon plasma at about 6000–10,000 K and measures the light each element emits. Measures many elements at once from trace to percent levels.

CALIBRATION

ICP-OES calibration procedures

Wavelength calibration

Aligns the spectrometer so that each element's emission line falls exactly where the software expects it, using a multi-element calibration solution.

Open procedure

Detection limit check

Measures the noise of repeated blank readings and converts it into the lowest concentration the instrument can reliably detect for selected elements.

QUALIFICATION

Instrument qualification (DQ · IQ · OQ · PQ)

  1. 01

    DQ — Design qualification

    Defines elements, required detection limits, axial/radial view, sample types (aqueous or organic) and software compliance needs.

  2. 02

    IQ — Installation qualification

    Confirms installation, utilities (argon, exhaust, chiller, power), components, software version and documentation.

  3. 03

    OQ — Operational qualification

    Tests wavelength calibration, resolution, detection limits, short- and long-term stability and linearity.

  4. 04

    PQ — Performance qualification

    Shows ongoing fitness, e.g. daily performance checks and system suitability for the validated <233> procedure.
