In the case of a dry powder absorbing water, the gravimetric sorption technique known as “dynamic vapour sorption” (DVS) assesses how quickly and how much of the solvent is absorbed by a sample. This is accomplished by altering the vapour concentration around the sample and observing the change in mass that results.
It is used in pharmaceutics for polymorphism analysis and salt screening. It is used in food research to examine moisture migration across ingredients in a food product as well as stability and shelf-life investigations.Benefits of Dynamic Vapour Sorption Over Conventional Methods.
Mix Saturated (100%RH) and Dry (0%RH) Carrier Gas Flows using Electronic Mass Flow Controllers. Single temperature zone: This guarantees constant humidity levels throughout the system. Excellent Baseline and Minimal Gas Buoyancy Effects due to Symmetrical Design.
The Global Dynamic Vapor Sorption Analyzer Market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
Water Vapor Sorption Analyzer: New Dynamic Model from Quantachrome Quantachrome Instruments’ new Aquadyne DVS-1 is the single sample variant of the classic dual sample Aquadyne DVS gravimetric water vapour sorption instrument.
In order to meet the needs of smaller materials R&D and characterization laboratories and those with fewer samples to be examined, the new DVS-1 model has been created.
Pharmaceuticals, food products, building materials, fuel cell and battery components, as well as adsorbents like activated carbon, zeolites, aluminas, and silicas, to mention a few, all have crucial properties that allow them to absorb water vapour. The high sensitivity (0.1 microgram) and high balance load capability of the Aquadyne DVS series are its distinguishing features. (up to 5g),
The Aquadyne DVS-1 and Aquadyne DVS-2 now come in single-sample and two-sample versions, respectively, and include a potent Peltier-driven heating/cooling thermostat and an easily accessible sample chamber. In the two sample version, two samples are analysed simultaneously in a RH/temperature controlled chamber, with each sample being weighed by a separate balance.
Since dynamic water vapour sorption is undoubtedly not a quick measurement, this design enables true simultaneous measurements, resulting in an obvious increase in analysis throughput. The new single sample Aquadyne DVS-1, however, offers a cost-effective solution to the analytical demands of those labs that don’t need that throughput.
