MEIS Lab, Building 131
Molecular Environmental Interface Science (MEIS) research at SSRL focuses on the fundamental interfacial, molecular- and nano-scale processes that control contaminant and nutrient cycling in the biosphere with the goal of elucidating global elemental cycles and anthropogenic influences on the environment. SSRL-based MES research utilizes synchrotron-based x-ray absorption spectroscopy (XAS), x-ray diffraction (XRD), small-angle x-ray scattering (SAXS), x-ray standing wave (XSW) spectroscopy, and photoemission spectroscopy (PES) because of their unique capabilities to probe structure/composition relationships in complex, non-crystalline, and dilute materials.
The sample preparation labs are maintained for final-stage sample preparation and other relatively straight-forward laboratory manipulations. These include buffer preparations, solid sample grinding, solution concentration, filtration, and centrifugation, and simple dissolution of solids. The user labs are presently not configured for chemical transformations.
The labs are divided into SSRL staff and visiting researcher areas. These areas include separate rooms in the bldg 120 lab, but are adjoint in the bldg 131 lab and the MEIS lab.
User lab bench spaces can be temporarily assigned to individual research groups. Learn more about laboratory access.
The MEIS user lab is located in room 113 on the ground floor of building 131. It is convenient to beam line clusters 4, 5, 6, and 11. A Coy anaerobic chamber for wet and dry sample preparation under (5%)H2/(95%)N2 atmosphere is available to visiting researchers. Learn more about resources available in the MEIS lab on our chemical information and equipment information pages.
As a reminder, researcher safety is taken seriously at SSRL. Please see our User Access Agreement and the SSRL Safety page for information regarding lab policies and practices.
