Typical Use:

Primarily used for quantitative spot analysis of minerals. BSE, CL, and X-ray maps for sample textures.

Conditions for Use:

Visitors are invited to work in the lab to work with lab personnel.

User Fees:

Usual fee for University students/faculty is $300/day plus an additional $100 if automated overnight. Normal hours open 8-5 M-F.

Remote Use:

Sample Preparation:

Preferred sample is a one inch round polished section. All samples must be Carbon coated at our lab at least 1 day before analysis. Standard petrographic slides (polished) may also be used.

Standard Collections/Lab Blanks:

A collection of Natural and Synthetic standards is available. Most elements from B-U are available.


Cameca SX100 software package on a PC platform.

Educational Use:
