Description

In the Pore Water Geochemistry Lab pore water from sediment samples is extracted using a hydraulic press with Titanium extractors. Extremely small (µl) volumes of aqueous samples are analysed with ion chromatographs for inorganic ions, cations and organic acids and a photometer.

Instruments

ION CHROMATOGRAPHS are recorders that are used in chromatography; a form of high pressure liquid chromatography using conductivity detectors where a combination of weak ionic solvents are used to separate anions and cations of a solution, with the contribution of the solvent to conductivity suppressed just prior to detection; measures anions such as sulfate, nitrate, and chloride in hydrometers.

IC - Ion Chromatograph
PHOTOMETERS are instruments used for measuring the luminance, luminous intensity, or luminance of a light source; similar to a radiometer, but with an output weighted by the wavelength response of the human eye.
