EQUIPMENT AND FACILITIES

Analytical Instrumentation

We have the following analytical instruments in the aqueous geochemistry laboratories:

	A Thermo Scientific iCAP 6300 ICP-AES (inductively coupled plasma-atomic emission spectrometer) with solid-sate detector and axial torch
	A Dionex ICS3000 ion chromatography work station with dual gradient pumps
	A Shimdazu UV-visible spectrophotometer
	A Perkin Elmer Spectrum 1000 FTIR spectrometer
	A Mantech automated titrator
	Assorted ion-specific electrodes (including pH electrodes) and several research grade pH meters

Within the College of Science at the University of Idaho we have access to:

	Transmission electron microscopy (TEM)
	Scanning electron microscopy (SEM)
	Powder x-ray diffraction
	Single-crystal x-ray diffraction
	Atomic force microscopy (AFM)
	Flame atomic absorption spectrometry (FAAS)
	Nuclear magnetic resonance spectroscopy (NMR)
	Raman and FTIR spectroscopy

Via reciprocal agreement with Washington State University (eight miles away) we have access to

	Electron microprobe analysis (EMPA)
	Inductively coupled plasma - mass spectrometry (ICP-MS)
	X-ray fluorescence (XRF)
	Stable isotope analysis

High-Temperature/High-Pressure Equipment

We have the following equipment for experimental geochemistry/petrology:

	Ten cold-seal pressure vessels with furnaces
	A flow-through hydrothermal apparatus consisting of a 100-mL, Bridgeman-type, A286 autoclave, a constant flow pump and furnace
	A Hydropac L'il Critter argon gas pump
	Two Bridgeman-type, 250-mL, gold-lined autoclaves constructed of alloy A286 with furnaces
	Twelve Barnes-type, 1-L, confined gasket-closure pressure vessels with six furnaces
	Six 300-mL, confined gasket-closure pressure vessels with three furnaces
	Two Blue M convection ovens and autoclaves for silica-tube solubility experiments
	A TIG arc welder for sealing precious metal capsules
	A hydrogen-oxygen torch for sealing silica tubes
	A hydrogen-electrode concentration cell suitable for potentiometric titrations or solubility measurements with in-situ pH measurement up to 300 °C (under construction)
	A wide variety of pressure gauges, temperature controllers and ancillary equipment for high-temperature/high-pressure experiments

With this equipment we can carry out a variety of solubility and phase equilibrium experiments at conditions ranging from ambient to 800 °C and 2000 bars.
