ICP & ICP-MS Standards
Inductively Coupled Plasma (ICP) is an analytical technique utilised in the detection of trace metals in a wide variety of matrices. Two main methods of detection are commonly used; ICP-OES (Optical Emission Spectroscopy) and ICP-MS (Mass Spectroscopy).
ICP-OES is predominantly used for samples with high total dissolved solids (TDS) or suspended solids and is, therefore, suited to analysis of ground water, wastewater, soil, and solid waste - although it can also be used for drinking water analysis. ICP-MS, on the other hand, is mainly used for analysing samples with lower regulatory limits.
Our ICP standards and ICP-MS standards are assayed by validated ICP and wet chemical procedures to obtain the certified value. The standards we offer for ICP and ICP-MS are traceable to specified NIST SRMs; The NIST-traceable density is shown on the Certificate of Analysis.
ICP-MS is becoming a workhorse for metal analysis in water not only because it offers lower detection limits. The following features also contribute to its wide range of environmental applications:
- Wide dynamic range
- Efficiently removes polyatomic spectral interferences using collision cell technology
- Rapid semi-quantitative analysis
- Isotopic analysis
- Speciation capability
ICP-OES is used for all the matrices of environmental samples especially for high-matrix samples. The following features also contribute its wide range of environmental applications:
- Only analytical grade reagents are sufficient
- Simpler method development does not need a specialist with highly technical expertise
- Overall is a cheaper option if the elements do not need lower detection limit that ICP-MS delivers
