Laser Ablation Analysis: LA-ICP-MS & LIBS
Rapid screening of major to trace elements in spatially resolved mode is often necessary. The identification of interfaces, defects, segregation pockets, fractures, interstitial fillings are a few examples. Be it regarding state-of-the-art or energy materials, bio-compatible matrices, or forensic micro-samples, our decennial expertise offers full quality and statitical robustness.

Spatially Resolved Materials Stoichiometry
Laser ablation microanalysis permits to quantifya material rapidly and without much preparation. It offers spatially-resolved capability with large dynamic range while combined with Inductively Coupled Plasma - Mass Spectrometry (ICP-MS). In Laser ablation a 10-500 micron sampling is performed, and the laser-induced aerosol is characterized online, by means ICP-MS or optical emission spectrometry (OES) also known as LIBS. Both LA-ICP-MS and LIBS are collected simultaneously for complete elemental coverage across the periodic table.
Additionally, we have access to Scanning Electron Microscopy for imaging of nanostructured materials. The semi-quantitative analysis is complemented with the use of X-ray Fluorescence Spectrometry for Mappings. The technique is run is so-called wavelength-dispersive mode to achieve excellent resolution and detection power.-
