This includes the measurement of oxygen and hydrogen isotope ratios in water as well as the speciation of Se, As and Sb redox pairs. We also analyze solutions of digestions or partial digestions/extracts of solids and provide a rudimentary description of the organic nature of water samples.</p> <p><strong>All analytical methods are available for external users.</strong> For further information please contact <a class="mail" href="mailto:c.hansen@uni-bremen.de" title="Öffnet ein Fenster zum Versenden der E-Mail">Dr. Christian Hansen</a>.</p> <p><a class="download-link" href="t3://file?uid=197820" target="_parent">User regulations</a></p> Content content-577371 Fri, 06 Mar 2026 12:19:13 +0100 https://www.uni-bremen.de/en/geochemistry-and-hydrogeology/laboratory#c577371 <p>Major anions</p> <p>(<a class="internalLink" href="t3://page?uid=64571" title="Opens internal link in current window">IC</a>)</p> Content content-577372 Fri, 06 Mar 2026 12:19:13 +0100 https://www.uni-bremen.de/en/geochemistry-and-hydrogeology/laboratory#c577372 <p>Major cations</p> <p>(<a class="internalLink" href="t3://page?uid=64270" title="Opens internal link in current window">ICP-OES</a>)</p> Content content-577373 Fri, 06 Mar 2026 12:19:13 +0100 https://www.uni-bremen.de/en/geochemistry-and-hydrogeology/laboratory#c577373 <p>Trace elements</p> <p>(<a class="internalLink" href="t3://page?uid=64572" title="Opens internal link in current window">HR-ICP-MS</a>)</p> Content content-577374 Fri, 06 Mar 2026 12:19:13 +0100 https://www.uni-bremen.de/en/geochemistry-and-hydrogeology/laboratory#c577374 <p>Isotopy <sup>18</sup>O/<sup>16</sup>O and <sup>2</sup>H/<sup>1</sup>H</p> <p>(<a class="internalLink" href="t3://page?uid=64582" title="Opens internal link in current window">CRDS</a>)</p> Content content-577386 Fri, 06 Mar 2026 12:19:13 +0100 https://www.uni-bremen.de/en/geochemistry-and-hydrogeology/laboratory#c577386 <p>Arsenic (As) und Antimony (Sb)</p> <p>(<a class="internalLink" href="t3://page?uid=64573" title="Opens internal link in current window">HG-AFS</a>)</p> Content content-577387 Fri, 06 Mar 2026 12:19:13 +0100 https://www.uni-bremen.de/en/geochemistry-and-hydrogeology/laboratory#c577387 <p>Mercury (Hg)</p> <p>(<a class="internalLink" href="t3://page?uid=64574" title="Opens internal link in current window">CV-AFS</a>)</p> Content content-577388 Fri, 06 Mar 2026 12:19:13 +0100 https://www.uni-bremen.de/en/geochemistry-and-hydrogeology/laboratory#c577388 <p>Organic carbon (TOC)</p> <p>(<a class="internalLink" href="t3://page?uid=64578" title="Opens internal link in current window">IR</a>)</p> Content
