Inductively Coupled Plasma Mass Spectrometry (ICP-MS) provides extremely high sensitivity analysis for almost every element excluding C, H, O, N and the Halogens. Results are given quantitatively from the ppt to the wt% range for every element present in the sample. Preparation for solid samples is following: sample is digested or dissolved usually in an acidic aqueous solution.

In ICP-MS analysis high temperature argon plasma is ionizing elements and the ions are separated by their mass to charge ratios. Then the number and masses of ions are counted.

Main Applications of XRD Analysis

  • Elemental content from :

natural-, sewage-, process-, household  waters etc.

Soluble solid sample types

Ideal Uses
  • Quantitative bulk survey analysis of major, minor and trace elements
  • High accuracy detection of major and minor elements in a large variety of materials
  • Quality and process control
Strengths
  • Large amount of elements can be covered with a single analysis
  • Automated  measurement  increases accuracy, precision and throughput
Limitations
  • The sample must be completely dissolved
  • In the mass spectra, common matrix elements and other molecules can interfere measurement of some elements.
  • Emission spectra could be complex and elemental interferences are possible if the mass number of the element is very close to that of another element
  • Multiply charged or polyatomic ionic species can cause difficulties in quantification
