Our mass spectrometry facility includes a Nu Plasma II MC-ICP-MS, a VG Sector 54 TIMS, and an Agilent 8900 QQQ ICP-MS. The lab also includes a Photon Machines femtosecond laser ablation system for in-situ analysis. Additionally, the lab features a suite of HEPA-filtered clean lab space to accommodate a range of radiogenic and stable isotope preparatory analysis.
Our primary focus is on high-precision isotope ratio measurements. We also measure major, minor, and trace-element concentrations in situ and via solution modes along with in situ chemical mapping. We have experience working on a variety of different sample types spanning across a range of natural science and engineering subdisciplines.
We are pleased to host outside visitors in our laboratory to help them with geochemical analysis. We function as a teaching research lab, so we encourage collaborators to visit the lab and learn the details of sample processing and data acquisition, when possible. We also process contract samples if the project aligns with our equipment/capabilities. If you are interested in collaborating with us, please contact Annie Bauer (annie.bauer@wisc.edu) and Mike Tappa (mtappa@wisc.edu). In your email, please include a description of: 1) the project goals, 2) sample type, 3) number of samples, desired elements and/or isotopes for analysis, concentration estimates, and any deadlines or time constraints.
