IGA Sorp series – Dynamic Vapor Sorption Analyzer

This post is also available in: viVietnamese

The IGAsorp has an ultra-sensitive microbalance which measures the weight of the sample as a function of humidity and temperature. Multiple sensors at the sample position allow precise feedback control of the experimental parameters. Humidity is determined by relative mixing of wet and dry gas streams which is measured and regulated at the sample position. The temperature is controlled by active feedback fluid circulation.

 Applications:
  • Pharmaceutical
  • Biotech
  • Polymers and packaging
  • Natural materials
  • Building and construction materials (cement, timber, insulation, adhesives)
  • Electronics
  • Fuel cells (proton exchange membranes)

Example Application Data
