Water sorption behavior plays an important role in the manufacture and design of many commonly encountered and advanced materials.

Some examples include:

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

Water sorption measurement has traditionally been either slow and laborious, or costly and limited to small quantities of material. The Hydrosorb 1000 is the latest innovation in water sorption characterization and overcomes these limitations. It offers fully automated, rapid measurement of adsorption and desorption water isotherms including BET surface area calculations and heats of adsorption. Two models offer analysis temperature ranges of 12deg to 47degC or 12deg to 85degC.  Accurate water vapor dosing is made possible by using a unique, heated (100° C) manifold design. HydroWin PC software provides convenient set-up of analysis parameters, data reduction and reporting.
