Optima 3000 DV ICP-OES

The Perkin Elmer Optima 3000 DV is an inductively coupled plasma optical emission spectrometer (ICP-OES).^[1]

In an ICP-OES, a liquid sample is introduced into an argon plasma that reaches temperatures of several thousand degrees Celsius. The high energy of the plasma atomizes the sample and excites the resulting atoms and ions, causing them to emit characteristic wavelengths of light specific to each element.

The emitted light is separated by a polychromator or echelle grating into its component wavelengths, and the intensity at each wavelength is measured by a detector such as a charge-coupled device. The measured intensities are compared against calibration standards to quantify the concentration of each element in the sample.

Upstream processes include sample preparation such as acid digestion or dilution. Downstream, the instrument generates concentration data used for process validation, contamination control, or regulatory compliance.

ICP-OES instruments are applied across industries including environmental monitoring, pharmaceuticals, metallurgy, petrochemicals, and semiconductor manufacturing for the analysis of trace metals and impurities. Typical applications include analyzing wastewater, drinking water, pharmaceutical raw materials, metals and alloys, and cleaning solutions.

In semiconductor fabrication, ICP-OES is used to monitor the purity of chemicals, plating baths, and rinse water, as well as to characterize thin-film composition and detect metallic contamination on surfaces.
