Below is the equipment list with short descriptions:

Agilent 5900 ICP-OES

  • Axial/Radial detection
  • ppb level detection for cation in aqueous solution
  • High throughput (~1 min/sample)

DigiPrep Junior Acid Digestion Block

  • DigiPREP Jr is a Teflon® coated graphite digestion block which can heat from ambient to 180 °C with temperature uniformity of ± 1.0 °C under ambient pressure. Comes complete with a 12-position RackLock rack for 100 mL borosilicate glass DigiTUBEs and controller

Malvern Mastersize 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, dust (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.

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 or moisture)

 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

Hamilton Microlab 600 Auto-diluter

  • Ideal for dilution ratios between 10 and 100
  • Diluent can be 5% nitric acid or DI water
  • Requires training from the APEC members before using
