H-calibration samples

For calibration of glow discharge spectrometers

For calibration of H-analyzers

For fundamental investigations of the H effect

Since many years there is a lack of suitable massive solid calibration samples for the element H. The IFW was successful in sintering 8 different mixtures of Cu und TiH₂ under vacuum and inert gas, which results in vacuum tight massive samples, useable like normal standard samples. E.g. also grinding is possible. Constant intensity ratios are generally achieved within 3 minutes pre-sputtering.

The H concentration was determined by carrier gas hot extraction with an accuracy of 5%. At the moment samples with 20 mm diameter and 5 mm height can be produced within the concentration range of 0.13 und 1.5 m%. These new H calibration samples are at the moment deliverable with 0.1 m%, 1.0 m% und 1.5 m% H. Further concentrations and sample shapes, e.g. pin type geometry, can be discussed.
