Geochemical preparation
Mae'r cynnwys hwn ar gael yn Saesneg yn unig.
We have a range of facilities for geochemical experimentation and preparation of rock, sediment and water samples for chemical analysis.
Clean laboratory
Our class-100 clean laboratory is primarily used for HF dissolutions for ICP-MS analysis. It contains two HF-resistant fume cupboards with programmable hot-plates and a MARS microwave dissolution system.
Multi-purpose laboratory
Our main geochemical preparation laboratory is equipped with three fume hoods and space for both geochemical experimentation and preparation of rock, sediment and water samples for chemical analysis. A Milli-Q Academic pure water system produces 18.2MΩ water for analytical and experimental geochemistry.
A geomicrobiological annex is adjacent to the main laboratory and is equipped with a class II microbiological safety cabinet and incubator.
To service analytical requirements, the laboratory houses a Claisse M4 fusion system for automated preparation of solid samples by lithium metaborate fusion and acid dissolution. Space and equipment are available in the laboratory for preparation and analysis of samples, including Edwards freeze dryer, Heraeus Megafuge 16 centrifuge, Miele professional glassware washer etc.
We have a small equipment room which contains one four-figure and two five-figure analytical balances for precise and accurate weighing of samples for analysis. In addition, the room houses a Cary 60 Ultraviolet-Visible (UV-Vis) spectrophotometer.
Gas chromatograph
A Perkin Elmer Autosystem Gas Chromatograph equipped with flame ionization detector (FID) and thermal conductivity detector (TCD) is set up for Natural gas analysis (H2, CO2, CH4 etc.)
Ion chromatograph
A Dionex ICS-5000+ Ion Chromatograph provides fully automated analysis of anions (Fluoride, Chloride, Bromide, Nitrite, Nitrate, Phosphate and Sulphate etc) and cations (sodium, potassium, ammonium etc) in water samples.
