Description
Laser system: An 193nm UV excimer laser ablation system for ablation of silicate, phosphate, oxide and carbonate minerals to make trace element and isotope ratio measurements by split-stream coupling the laser system to a multi-collector inductively-coupled plasma mass spectrometer and a collision cell “triple quad” inductively-coupled plasma mass spectrometer. Ideally it would have an integrated LIBS detector and the ability to pair LIBS and LA-ICPMS analyses. We require a 193 nm, short pulse (<7 ns) excimer laser system, capable of delivering a variable sized, homogeneous beam to produce reproducible, sharp-sided ablation pits in a range of matrices including: silicate, phosphate, carbonate and oxide minerals. A two-volume sample chamber is required to allow efficient transfer of ablated material from samples of a range of sizes to the mass spectrometer(s) with rapid wash out to allow for efficient compositional imaging. The ablation system will come with automated control of laser …
