Quantachrome Instruments’ new Aquadyne DVS-1 is the single sample version of the original dual sample Aquadyne DVS gravimetric water vapor sorption instrument. The new DVS-1 model has been developed to address the needs of the smaller materials R&D and characterization laboratories and those with fewer samples to be analyzed.
Water vapor sorption is an important property of a wide variety of materials such as pharmaceuticals, foods, building materials, battery and fuel cell components, adsorbents like activated carbon, zeolites, aluminas and silicas to name but a few. The Aquadyne DVS series is characterized by its high sensitivity (0.1 microgram) combined with high balance load capability (up to 5g), a powerful Peltier-driven heating/cooling thermostat, easily accessible sample chamber, and now a choice of a single-sample version, the Aquadyne DVS-1, or a two-sample version, the Aquadyne DVS-2. The two sample version analyzes two samples in parallel in the same RH/temperature controlled chamber – each sample being weighed by its own balance. This configuration provides for true simultaneous measurements resulting in an obvious increase in analysis throughput – dynamic water vapor sorption is admittedly not a rapid measurement! But for those labs that don’t require that throughput, the new single sample Aquadyne DVS-1 is a cost-effective solution to their analytical needs.
