Inductively Coupled Plasma
(ICP-OES)

This technique offers an alternative to XRF and conventional OES when sample size is limited or the sample form is unsuitable (e.g. turnings, fine wire or powder). The analysis involves dissolution of the sample, and therefore it is relatively easy to prepare closely matching calibration standards from pure metals and compounds. This is particularly important where appropriate CRMs are not available or where an independent overcheck is needed.

Gas Analysis

Oxygen, Nitrogen and Hydrogen levels are determined by the Inert Gas Fusion method. The sample is melted under an inert gas stream in a graphite crucible and the gases evolved are measured by thermal conductivity or infra-red absorption. The instrumentation is calibrated for both Nickel/Cobalt/Iron base and Titanium base materials.

Carbon and Sulphur Analysis

Carbon and Sulphur are determined by RF combustion in oxygen. The resulting carbon dioxide and sulphur dioxide are then measured by infra-red absorption and converted to the elemental concentrations.
