Certain services and equipment are available for use on a fee-for-service or collaborative basis, including:

Analytical Equipment:

TESCAN VEGA3 LMU SCANNING ELECTRON MICROSCOPE

A variable pressure tungsten filament TESCAN VEGA3 LMU scanning electron microscope that can be operated in both a high-vacuum mode for maximum image resolution of coated samples, as well as a low-vacuum mode that enables investigation of non-conductive specimens in their natural, uncoated state.

An attached OXFORD X-MAX 80 Energy Dispersive Spectrometer (80 mm² EDS) can be utilized to analyze and map most elements on the periodic table down to 100 ppm concentrations and 1 micron spatial resolution. An attached OXFORD NORDLYS-NANO Energy Backscatter Diffractometer (EBSD) can be used to analyze and map mineralogy and crystal structure down to 1 micron spatial resolution.

Hourly rates (external/internal):

SEM: $60/$40

SEM + EDS/EBSD: $120/$90

SEM + EDS + EBSD: $180/135

 

RIGAKU MINIFLEX 600 X-RAY DIFFRACTOMETER

A RIGAKU MINIFLEX 600 X-ray diffractometer for powder x-ray diffraction with Rietveld refinement to assist with determination of mineralogical identity and quantity, percent crystallinity, crystallite size and strain, lattice parameters, and molecular structure.

Hourly rates (external/internal): $25/$20

 

EXPERIMENTAL CULTURING ARRAY

Fully controllable 72-tank array for culture experiments to assess the impact of acidification, temperature, salinity, nutrients, and light on marine organisms. Available for flow-through or recirculating operation utilizing either fresh or salt water.

Rates per tank per month (external/internal): $50/$40

 

ANALYSIS OF SEAWATER DIC AND TA

VINDTA 3C with UIC COULOMETER for the analysis of TA (total alkalinity) and DIC (dissolved inorganic carbon) of water. TA is analyzed by closed-cell potentiometric Gran titration. DIC is analyzed by coulometry. Minimum sample size is 250 mL, stored in ground-glass stoppered borosilicate bottles sealed with vacuum grease.

Rates for combined TA/DIC analysis per sample (external/internal): $60/$50

 

LIGHT MICROSCOPY

NIKON LV100 Polarizing light microscope equipped with head-cooled digital camera for high resolution imaging and photomicrography of petrographic thin-sections. Polarizing microscope is outfitted with a fluorescence module in order to visualize calcein markers (and other wavelength-compatible dyes) within thin-sectioned material.

 

 

 

NIKON AZ100 stereomicroscope equipped with automated z-stage and head-cooled digital camera for high resolution wide-field fully-focused 2D and 3D imaging and photomicrography.

 

Hourly rates (external/internal): $20/$15
