Keck Microanalysis Laboratory

Sonoma State University received an award from the W. M. Keck Foundation around the turn of the millennium, which opens new worlds of research on the molecular and atomic level for students, faculty, area junior colleges and high schools, and the local high tech community. The goal of the lab is to attract the North Bay high tech and biotechnology industry as well as researchers in the fields of physics, chemistry, material science, engineering, geology, and so on.

The 2,430 square foot Keck laboratory is housed in 15,000 sq. ft. of Salazar Hall, along with other labs in the Cerent Engineering Science Complex.

The Microanalysis laboratory houses the following instruments:

  • Janis cryotat, which runs temperature from room temperature to 15 K
  • Keysight (originally Pacific Nanotechnology) Atomic Force Microscope (AFM)
  • Ocean Optics Laser Induced Breakdown Spectrometer (LIBS)
  • Pelco Sputter Coater 91000 Model 3
  • PHI Auger Electron Spectrometer (AES)
  • Rigaku Powder X-ray Diffractometer (XRD)
  • Tescan Vega 3 Scanning Electron Microscope (SEM) with Energy Dispersive X-ray Spectrometer (EDS/EDX)

If you are interested in using any of the instruments, please feel free to contact Dr. Hongtao Shi. As the Keck lab is self supporting, we ask for a donation to the lab at a cost of $125 per hour of work. The money collected will pay for operating expenses, Nitrogen gas, and replacement parts as needed. Please keep in mind that our technicians work full time jobs supporting students, so the turn around on Keck lab analysis may take more time than other companies or institutions and is subject to cancelations.
