Laser Microanalysis

Spot-resolved analysis is required to characterize the heterogeneity of solid materials, which can be done with a number of techniques (Fig. 1). By means of Laser ablation, coupled with various detectors (Fig. 2), spatially resolved analysis in the range of µm is feasible in a rapid and handy way. No special sample preparation is needed, and results are available within minutes. The sample is directly ablated by the laser, and in LIBS (Laser-Induced Breakdown Spectroscopy) the generated plasma-radiation is spectrographically analyzed; the ablated material, transported by a carrier gas, is analyzed by ICP-MS (plasma mass spectrometry) or ICP-OES  (plasma emission spectrometry) to achieve trace-level detection power and isotopic resolution.

We elaborated and further developed our laser microanalysis setup to measure in an automated and efficient way the largest possible element menu. To extend the specific analysis capabilities, detection via ICP-MS, ICP-OES and LIBS system is being integrated within a single system. Out “LasMAT” multi-spectroscopy system enable the analysis for a wide range of elements and materials, from metal to ceramic till polymers and biological samples, within a single laser shot.
