Our Sample Preparation Laboratory is well equipped with a suite of work stations for research in the geological, physical and electron microscopy sciences.
The laboratory helps us to promote, support and initiate research and teaching through preparation and processing of geological and environmental samples for textural and chemical analyses of solid samples. It is widely used by our students, research and industry partners.
The Laboratory stations house a sectioning and polishing equipment that you can use to produce high-quality thin and thick sections of inorganic solid specimens for electron microscopy and solid chemical analyses.
The lab specializes in 1-inch samples, 90% of the samples used in the EPMA and LA-ICP-MS are 1” (outside diameter) rounds or geological thin and thick sections.
Sample sizes that can be accepted by the analytics instruments:
· Epoxy mounts: 1 inch in outside diameter and 1 inch in depth.
· Thin and thick sections: 4.5 cm long by 2.6 cm wide.
· Large flat samples can measure 7.5 cm long by 3.5 cm wide and 2 mm thick.
· There are a few other sample sizes that can be accepted; ask if you have questions.
The following tools are available for the treatment of the samples:
