The BGPS Analytical Lab is home to a Scanning Electron Microscope (SEM), X-Ray Diffractometer (XRD), X-ray Fluorescence Spectrometer (XRF), and polarizing and stereo microscopes. Read more about the equipment below.

Equipment is available to all students, faculty, staff, and members of the public for a broad array of basic education and research. Most equipment use is fee-based.

Science education at Sul Ross State made an exciting advance in April 2013 with the delivery of a state-of-the art Scanning Electron Microscope (SEM). The SEM is administered by the Analytical Lab Technician in the BGPS department at Sul Ross.

The SEM adds significantly to the school’s research capacity. “A student attending a larger school probably wouldn’t get close to an SEM as an undergrad," said Dr. Kevin Urbanczyk, Professor of Geology and lead for the Analytical Insrumentation course.
