GFZ - German Research Centre for GeosciencesThe EleMap Lab is devoted to in situ analyses of minor and trace elements in minerals and other geological materials. We have a Teledyne Analyte Excite 193 nm excimer laser coupled to a Thermo Scientific iCAP RQ quadrupole ICP-MS and a Thermo Scientific iCAP TQ quadrupole ICP-MS, which can filter masses through the use of a reaction cell (MS/MS). The Laser system delivers a fully homogenized laser beam which ensures uniform ablation across the entire range of spot sizes with ns pulse length (< …
GFZ - German Research Centre for GeosciencesThe UV fs laser ablation lab at HELGES is a state-of-the-art facility for the in situ micro-scale analysis of isotope ratios and element concentrations in a wide range of solid geological and environmental materials (rocks, minerals, soils, meteorites, biogenic silica- (phytoliths) and calcium carbonate-producing organisms).
Femtosecond lasers ablate with minimal thermal heating to the surrounding area of the crater due to the short laser pulse length compared to the photon relaxation …
