The laboratory was established in to provide a more or less complete inorganic analysis of aqueous samples, such as, groundwater, seawater and hydrothermal solutions. This includes isotope ratio determination for oxygen and hydrogen of the water molecule and speciation of the Se, As and Sb redox couples. We also analyze sythetic solutions resulting form dissolution or partial dissolution of solid materials and carry out a rudimentary organic description of water samples.


More detailed descriptions of analytical methods and instrumentations can be found here:

  • Major anions by ion chromatography (IC)

  • Major cations by inductively coupled plasma-optical emission spectrometry (ICP-OES)

  • Trace elements by high resolution-inductively coupled plasma-mass spectrometry (HR-ICP-MS)

  • Arsenic (As) and antimony (Sb) by hydride generation-atomic fluorescence spectrometry (HG-AFS)

  • Mercury (Hg) by cold vapor-atomic fluorescence spectrometry (CV-AFS)

  • Total Organic Carbon (TOC) by non-dispersive infrared detection (IR)

  • Isotope ratios of oxygen and hydrogen by cavity ring down spectroscopy (CRDS)
