ICP Analysis

ICP analysis is an element analysis method; it includes ICP-OES and ICP-MS.

ICP stands for inductively coupled plasma; its working principle can be shown in the following picture.

Standards

ICP-AES

  • ASTM E2371
  • ASTM E2594
  • ASTM E3061

ICP-MS

  • ASTM E2823

Calibration

Sigma Aldrich provides standard solutions for calibration (link). Inorganic ventures also supply standard solutions.

Limitations

The only elements which cannot be measured by ICP methods are C, H, O, N and the halogens.
