Vapor Sorption Analyzers

Water sorption kinetics, and percent water uptake are all characteristics of interest to material scientists interested in exploring how water sorption impacts material characteristics, shelf life, performance, and stability. Water sorption behavior plays an important role in the development, use, and stability of many common and advanced materials. These characteristics cross a wide variety of material types, applications, and industries.

Some common examples of applications and uses of water sorption analysis include:


•  Stability of pharmaceutical excipients and drug actives.
•  Drying and storage of grains.
•  Texture and shelf life of food products.
•  PEM fuel cell components.
•  Mortar, grout and other cementitious materials.
•  Paper and coatings.
•  Hydrophobic surface treatments.
•  Microporous and nanostructured carbons.
•  Ceramics and fired clay.
•  Organic vapor sorption.

VSTAR


Vapor sorption analyzer dedicated to the analysis of materials using water and organic vapors. A single thermostatically controlled chamber houses the vapor source and manifold and independently controlled sample cells provides the best temperature control available for the most accurate analyses. The VSTAR™ is available in 1-,2-,3-,or 4 station model(s) to fit your needs. more...

Water & Organic Vapor Sorption Analyzer
Dynamic vapor sorption (DVS) analyzer for water sorption isotherms

Aquadyne™DVS-1, DVS-2, DVS-2HT


The Aquadyne™ DVS is a fully automated, gravimetric, one or two sample, dynamic vapor sorption analyzer. It measures adsorption and desorption isotherms of water vapor both accurately and sensitively, including sorption kinetics, with minimal operator involvement. more...

Autosorb iQ® with Vapor Option


Manometric (static, volumetric) analyzer for gas and vapor physisorption measurements. Typical vapors include water, alcohols, and aromatics. The vapor generator is housed within the manifold chamber... heated and thermostatically controlled. A solenoid valve opens the pump ballast for all-important venting of condensible vapors. The vapor option is available on all models of the Autosorb-iQ, one- and two-station versions. more...
