The Sercon Aqua is a high performance equilibration system optimised for the precise measurement of the stable isotopes of hydrogen and oxygen isotopes in water. The Aqua is available in both continuous flow and dual inlet mode and provides optimal performance for a wide range of samples, including fruit juices, wine, and other aqueous solutions. Gas samples may also be measured such as breath or biogas. Up to 220 samples may be analysed in a single unattended run. The heated sample block in which the vials are placed is temperature controlled to within 0.1°C to ensure precise data for temperature dependent equilibration reactions. δ18O and δ2H measurements are made via headspace equilibration with CO2 and H2 respectively. These measurements can be made separately or sequentially. δ2H measurements require the use of a platinum catalyst which is provided with the system. When interfaced to the Sercon HS2022 (continuous flow) or GEO-HS2022 (dual inlet), the Aqua provides excellent precision, high sensitivity, and exceptional performance with minimum maintenance.
