MI-Chron LA-ICP-MS lab<\/h2>\n\n\n\n

Our LA-ICP-MS laboratory is used for trace-element analysis, mapping, and U\u2013Pb petrochronology of solid materials. The lab uses an Agilent 7900 quadrupole ICP-MS with an ESI NWR193 excimer laser-ablation system. We are not a commercial lab or user facility, but we welcome users for collaborative scientific research. Contact Robert Holder (roholder@umich.edu).<\/p>\n\n\n\n

Pictured below: U\u2013Pb titanite concordia diagram. REE profiles from spot analyses of garnet. Lu concentration map of garnet (20 um spot, 7×16 mm; warmer colors are higher concentrations, 0.1\u20136.5 ppm). Laser sample cell.<\/p>\n\n\n
