Instrument Type

XRD

Rigaku MiniFlex II

Application:

  • Mineral composition
  • Mineral structure (atomic)

Typical Use:

Identify mineral phases in solid samples, including whole-rock powders and slabs; characterize structure of crystalline materials; use atomic structure to identify nature of solid solution in minerals.

Conditions for Use:

  • Visitors are invited to work in the lab to work with lab personnel
  • Visitors are invited to work in the lab to design and do the work yourself
  • Training Session (short course) is offered

User Fees:

Outside users are charged $15/hour for x-ray time, but fees may change at any time; contact lab manager for current rates.

Instrument Priorities:

Priority is given on a first-come-first-served basis; an online calendar is maintained on the website; contact lab manager to schedule times.

Remote Use:

Standard Collections/Lab Blanks:

Standardized to silica.

Software:

Data are processed with PDXL software, which includes applications for search-match, quantitative analysis, percent crystallinity, crystallite size and strain, and cell refinement.

Educational Use:

  • Class demonstrations are available for undergraduates
  • Class demonstrations are available for K-12
  • Undergraduate student research projects are invited
