A flow system for transient gas measurements with a Balzers mass spectrometer and computer data acquisition. This system can rapidly switch between flow streams and is designed with minimum hold-up volume for rapid response.

A flow system for transient pervaporation measurements with a Balzers mass spectrometer and computer data acquisition.

Three continuous flow systems with GC detection (computerized) for measurements of single gas permeation and of mixtures separations. Two GCs have thermal conductivity detectors and the third has both thermal conductivity and flame ionization detectors. One system is designed for high pressure operations (1000 psia) and the other two for medium pressure use. All are designed for elevated temperature operation. One system is equipped for liquid feed, which is evaporated into a carrier gas, and the system lines are heated to prevent condensation. Two systems use a helium carrier gas on the permeate side of the membrane to maintain a concentration gradient and the third uses pressure drop as the driving force.

A computerized, single-gas permeation system with mass flow meters and a valving system. A Labview program records permeation rates as a function of time. This system has an oven that allows permeation measurements at elevated temperatures.

A small flow system for single gas permeation measurements.

A pervaporation system that can be run at elevated temperatures and two stand-alone GCs for analysis of permeate.

Autoclaves and ovens for zeolite membrane synthesis, and high-temperature ovens for membrane calcination.

An atmospheric-pressure flow system connected to a Balzers QMG 420 mass spectrometer. The mass spectrometer has computer data acquisition. This system is used for isothermal transient reaction, TPD, TPO, TPH, steady state reaction, and steady-state transient isotope tracing.

A Nicolet FTIR model 750, series II spectrometer and a reactor cell for transmission FTIR.

A Quantachrome model AUTOSORB Automated Physisorption and Chemisorption System can be used for measurements of BET surface area, Langmuir surface area, adsorption and/or desorption isotherms, pore size and surface area distributions, micropore volume and surface area using built-in data reduction procedures.

X-ray diffraction (XRD) is located in Professor Gin's laboratory: INEL CPS 120 system, which can be used for powder, pole figure, thin film, and single crystal analysis. It can collect diffracted X-rays up to 120o2 simultaneously.

Electron microprobe EPMA: JEOL JXA-8600 Superprobe is in the Geology Department

Scanning electron microscope is in both Geology and Physics
