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

Some examples include:

• Drying and storage of grains
• Shelf life of food products
• Stability of pharmaceutical substances
  
• Effectiveness of coatings for dental stain resistance

Quantachrome's Hydrosorb™ 1000

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. Sample temperature is thermostatted in the range 12-47?C and accurate water vapor dosing is made possible by using a unique, heated (100?C) manifold design. The fully integrated control system provides color real-time status, graphical data review and reporting functions via built-in color monitor and printer port. Data (ASCII format) can be uploaded to a PC via RS232 for importing into popular spreadsheet programs for further manipulation.
