WHOLE ROCK ANALYSIS - ICP Inductively-coupled plasma spectrometer +/- mass spectrometer (ICP-MS) and laser source

Micromass (GV) Platform ICP-MS

Whole-rock analysis (major and trace element)

The ICP-MS Laboratory is a University-wide facility managed by the Department of Geological Sciences. Our most common applications in geology use concentric nebulizer (for digested lake sediments and waters) and laser ablation (for fused XRF rock glass disks, minerals, and volcanic glasses). We routinely analyze trace elements used for low temperature and high temperature geochemical modeling.

Submitted samples will be analyzed on a contract basis (i.e. lab personnel will do the work).
Visitors are invited to work in the lab to work with lab personnel.

Charges will be made based on the user needs

All users are welcome

No

Solutions: should be stored in acid cleaned Nalgene bottles in 2% to 5% HNO3 solution. At least 5 mL are needed.
Rocks: low dilution fused glass disks (3:9 sample: flux) work best. Disks need to be kept dehydrated (in desiccators). Usually these analyses are done in conjunction with XRF to determine trace element concentrations. We need to know the concentration of at least one element in the sample.
Mineral and Volcanic Glass: minimum spot analysis is 25 microns. We need to know the concentration of at least one element in the sample.

Solutions: standards prepared from standard solutions, with matrix match. The user needs to bring a blank from their lab.
Rocks: USGS and Japanese standards are used to generate calibration lines. If samples are prepared at the user's lab, he/she should bring standards.
Mineral and volcanic glass: NIST and USGS standards are used

Data output will be in Excel or TXT format.
