LabSEAL A simple way for determining the chemical composition of solid samples

Ref-Nr: TA-M029/2016


Kurzfassung

Es handelt sich um eine neue Art der Laser- basierten Analyse von Feststoffen: die online- Analyse von durch den Laserabtrag erzeugten Partikel ist der Kernaspekt, ebenso die Entwicklung und das Design einer geeigneten Mikro- Auswaschzelle.

Problemstellung

Advanced materials are nowadays used in a wide range of research applications, as well as for industrial purposes. Particularly in the form of thin films, they offer promising perspectives. Chemical composition essentially influences their physical properties (e.g., electric conductivity, corrosion resistance) of the material which makes correct assessment necessary – in most cases a non-trivial task. Commonly applied techniques either lack in ease of use, accesibility, or adequately accurate quantification.


Lösung

LabSEAL helps to mitigate current limitations by combining simple quantification without requiring excessive sample preparation. The sample of interest is placed inside a liquid-purged compartment, the ablation cell. Subsequently, a highly energetic pulsed laser beam is used to convert parts of the sampleinto nanoparticles, which are then transported towards a spectroscopic detection device using the liquid carrier flow (setup illustrated in figure above).

Accurate determination of the sample composition can be easily performed

using aqueous standard solutions which are injected using a sample loop. Besides bulk analysis, also depth profiling and laterally resolved measurements are planned in future designs of the LabSEAL system
