Analysis in metallurgy

Modern high performance materials, such as ceramics, glasses and specific alloys are subject to the highest purity requirements. Even contaminations in the lower mg/kg range can significantly limit the material‘s performance for the desired purpose of use. A highly sensitive and precise analysis method
is required – solid AA^®!

The analysis of specific trace elements in alloys that are used to manufacture aircraft turbines is decisive in ensuring the reliability of the components. Due to the extreme centrifugal forces that act on turbine blades, specific elements build up in different zones where they can lead to material fatigue. This analysis is a difficult challenge for many methods.

While preparing the sample by conventional methods, make sure that it is not contaminated by reagent blank values. Element loss due to the formation of volatile species or due to adsorption must be excluded. In the case of a wet-chemical digestion, moreover, the sample is diluted to a degree that often makes it quite difficult to attain the required determination limit.

With solid AA®, the unaltered original sample is analyzed to avoid any risk of contamination. The measurement sensitivity is increased, since a dilution of the samples is not required. The resulting advantages are valuable for the material analysis.
