Laser Microprobe Mass Analyzer (LAMMA)

The Laser Microprobe Mass Analyzer (LAMMA) is a sophisticated technology for the surface analysis of materials. This instrument combines the power of laser ablation with the sensitivity of mass spectrometry to provide precise insights into the chemical composition of surfaces.

In surface analysis with LAMMA, an intense laser beam is directed at the material surface. This laser beam causes ablation, which removes tiny particles from the surface. These detached particles are then detected by the mass spectrometry unit, which analyzes their mass and ionic composition.

An outstanding feature of LAMMA surface analysis is its high spatial resolution. The laser beam can be aligned extremely precisely, making it possible to analyze microscopic areas of the surface. This capability is particularly valuable when investigating local differences in the chemical composition of material surfaces.

The areas of application for LAMMA surface analysis are diverse. In materials science, it enables the detailed characterization of surface structures, including coatings and thin layers. In biomedicine, LAMMA is used to examine tissue samples and implant materials. This technology is also used in the semiconductor industry to check the quality of surfaces in microelectronics.

Due to the precise information that LAMMA provides about the chemical composition of surfaces, this technology has become an indispensable tool for surface analysis in various scientific and industrial fields.
