Inductively Coupled Plasma Optical Emission Spectrometer

Perkin Elmer Optima 4300DV

nductively Coupled Plasma (ICP) is an analytical technique used for the detection of trace metals. Sample is introduced to an argon plasma whose temperature is 6000°K-10000°K. In the plasma, molecular bonds are broken, atoms and ions are formed. These atomic and ionic species are excited and are rapidly relaxed to emit at their characteristic wavelengths. Emission signals are analysed using an Echelle polychromator using a S-CCD (Segmented Charge Couple Device) array detector system. Detection limits are in the range of µg/L. Multi-element detection is possible.

Specifications

• Torch: Demountable design using one-piece quartz tubing for plasma and auxiliary gas flow. 2 mm alumina injector corrosion resistant to all acids, including HF and aqua regia.
• Spray Chamber: Scott-type, constructed of Ryton, resistant to most acids, including HF and organic solvents.
• Nebulizer: Cross-flow design. The system is compatible for use with other nebulizers.
• Polychromator: The high energy (f/6.7) echelle-based polychromator is PE design.
• Detector: The patented PE segmented-array charge-coupled device.

Sample requirements

Detailed information should be given about the samples; such as the composition of matrix, expected concentrations, legally required concentration level. If the sample is brought in solution,a blank should also be supplied with the sample.

Applications

Aqueous samples such as drinking water, wastewater and other samples relevant to fields of environmental studies, petrochemistry, food, hydrogeology and others.
