Laser Ablation Mass Spectrometry

Laser Ablation/Ionisation Mass Spectrometry (LIMS) is the ideal technique for the direct-sampling of the chemical (elemental and isotope) composition of any class of solid material. By applying pulsed laser systems for sample ablation and ionisation of sample material layer by layer the method is the most cleanest of all other sample preparation methods (no chemicals are used, no ovens are required). The lateral resolution (µm-level) and depth profiling (nm-level) can be flexibly adjusted by controlling the laser ion source conditions. Moreover, the method can be classified as quasi non-destructive because of the very low sample consumption ranging from 10-18-10-15 grams.

In comparison to earlier LIMS systems improvements of the performance of IONIGHTs laboratory LIMS systems were achieved by applying different laser sources (ns-, ps, to ultra-short pulsed fs laser systems), and separation, confinement and detection of ions. The home-built systems take advantage of the current knowledge of the laser plasma process, advances in theoretical modeling and modern technical solutions to ion separation, and new electronic and detector technology. Therefore, many obstacles deteriorating the performance of early LIMS systems were overcome. IONIGHTs LIMS systems offer high mass resolution, high dynamic range, accuracy, and precision of elemental and isotopic composition.

IONIGHTs LIMS system is well recognized by the science community and realised in 2013 two covers in world-renowned mass spectrometry journals (J. Mass. Spectrom., Vol. 48, No. 1, 2013;  J. Anal. At. Spectrom., Vol. 28, No. 8, 2013).
