Laser-Ablation Split-Stream
This Plasma facility enables LASS (laser ablation split-stream) analysis: simultaneous geochronology and trace-element geochemistry with 10-50 micron spatial resolution. The LASS facility consists of
- Nu Instruments Plasma 3D multi-collector ICP with sixteen Faraday cups, 5 low-mass Daly dectors, and one high-mass Daly detector
- Nu Instruments Plasma HR-ES multi-collector ICP with twelve Faraday cups and four low-mass ion counters
- Agilent 7700X/S quadrupole inductively coupled plasma mass spectrometer
- Cetac / Photon Machines 193 nm excimer Analyte laser with HelEx cell
Associated Instrumentation
The LASS facility is supported by extensive associated Earth-Science instrumentation, including
- Cameca SX-100 electron microprobe with 5 WDS detectors, an EDS detector, and a CL detector
- FEI Quanta 400f field-emission, environmental scanning electron microscope with an EBSD detector, BSE detector, SE detector, EDS detector, and a CL detector
- Thermo Fisher Triton thermal ionization mass spectrometer
- Class 100 Clean Room suite
- petrographic microscopes, cameras, and thin-section scanning equipment
- rock crushing and mineral separation facilities
