Below is the equipment list with short descriptions:

Inductively Coupled Plasma Optical Emission Spectrometer (ICP – OES)


  • Agilent Dual View 720

  • Capable of detecting cations in aqueous solution at concentrations as low as 1 ppb

  • Compared to atomic absorption techniques ICP-OES has greater speed, precision, and sensitivity

  • Full wavelength coverage 167 – 785 nm

 Milestone ETHOS EZ Microwave Digestion System


  • Advanced pressurized closed vessel microwave acid digestion system used to digest (dissolve) solid samples at 220°C prior to elemental analysis

  • Ensures evenly heated samples, short run times, and consistent digestion

  • Quartz inserts allow for HF media as well

Malvern Mastersizer Particle Size Analyzer


  • Excellent tool for particle size characterization based on laser diffraction technique

  • Measure particle size distributions of solid particles, bubbles or emulsions dispersed in liquid medium, dusts (dry powders) in air and sprays (aerosols)

  • Detection range of the instrument is from 0.05 to 900 μm

  • Samples will be suspended and stirred in water before entering the laser chamber

  • Ideal for particles that are non-reactive in water and insoluble in water

  • Non-ideal for particles that dissolve, react, agglomerate or form bubbles when suspended and stirred in water, unless the objective is to investigate the particle/bubble size distribution after such changes have occurred



  • Parr Instruments 2 L, 1 L-windowed and 0.6 L titanium autoclaves

  • Equipped with online sample withdrawal systems, temperature control, acid injector units, oxygen flow and pressure controllers

  • Titanium provides excellent corrosion resistance in a variety of applications

Fisher Scientific Isotemp Vacuum Oven


  • Designed to maintain constant temperature up to 200°C for sample drying, and with the possibility of achieving advanced vacuum (for samples sensitive to air oxidation)

Shaker Incubator


  • Accommodates an adjustable number of flasks and/or beakers (depending on size) and is designed to maintain a constant temperature (up to 80°C) and agitation (up to 1200 rpm) for prolonged periods; useful in solubility studies or bio-leaching experiments

Differential Scanning Calorimeter


  • High performance instrument adapted to isothermal calorimetry and temperature scanning calorimetry

  • Investigates materials transformation over a temperature range from ambient to 300°C

  • Can be applied for studies of thermal stability, mixing, evaporation, gas-liquid-solid reactions including pressure processes
