Groundwater contains many components such as organics or salts. Using a headspace equilibration technique allows the oxygen-18 and hydrogen-2 isotopes to be analysed whist avoiding interference from these other components. Our iso FLOW system provides exceptional headspace analysis performance for these samples.
The fastest and simplest analysis of fresh water samples is via direct injection of the sample into a furnace system. Our vario PYRO cube Elemental Analyzer equipped with the vario LIQUID sampler allows oxygen-18 and hydrogen-2 isotope analysis separately or sequentially for the fastest throughput. Using our ChromeHD technique uniquely offers the highest precision hydrogen-2 measurement possible.
Beyond oxygen and hydrogen isotopes measurements, analysis of the dissolved organic carbon, inorganic carbon and organic nitrogen can provide valuable insight in to primary productivity in freshwater ecosystems as well as polluting anthropogenic inputs. Our new iso TOC cube is the only system able to analyse both carbon and nitrogen isotopes in water samples at low concentrations.
