INDUCTIVELY COUPLED PLASMA- MASS SPECTROMETER (ICP-MS)
1. Equipment Name: INDUCTIVELY COUPLED PLASMA- MASS SPECTROMETER (ICP-MS)
2. Equipment Details: Make: Thermo scientific Model: X series II
Some applications of solution ICP-MS include:
- Geological studies: trace element analysis of rocks, sediments, soils and soil leachates mineral separates
- Environmental analysis: trace element analysis of fresh, saline and sediment pore waters
- Clinical analysis: trace element analysis of human teeth and bones, food, fish bones, blood.
- Metallurgical studies: semi-conductor materials, metals, archaeological materials, ceramics, etc.
Strengths:
- Excellent detection limits
- Multi-element
- High productivity
- Very economical for many samples and/or elements
- Wide dynamic range
- Isotopic measurements
Limitations:
- Method development skill is required
- Higher initial capital cost
- Some spectral interferences, but well defined
- Limited to <0.2% dissolved solids

Principle: ICP-MS is a multi-element technique that uses an ICP plasma source to dissociate the sample into its constituent atoms or ions. The ions are extracted from the plasma and passed into the mass spectrometer, where they are separated based on their atomic mass-to-charge ratio by a quadrupole or magnetic sector analyzer and detected by electron multiplier.
