Analytical Capabilities

Quality

Our ultra pure products with impurities down to “parts per million” (ppm) or even “parts per billion” (ppb) require comprehensive in house analytical capabilities. These methods are regularly cross-checked against standards and third party results.

The following methods are generally applied:

Crude chemical assays:
classical wet analysis, atomic absorption spectrometry (AAS), inductively coupled plasma spectrometry (ICP)

Trace determination:
glow discharge mass spectrometry VG 9000 (GDMS), wet trace analysis in clean room environment

Optical methods:
infrared spectroscopy, laser spectroscopy

Electrical methods:
resistivity, conductivity type, determination of other electrical properties
