Vapor Sorption Analysis
TA Instruments offers the most sensitive, versatile and productive moisture sorption analyzers on the market.
Vapor Sorption Analysis is a technique in which a sample is subjected to varying conditions of humidity and temperature, and the response of the sample is measured gravimetrically. Understanding the effects of water content on structure and properties is critical in the development, processing and end use of a broad spectrum of materials. TA Instruments offers the most sensitive, versatile, and productive moisture sorption analyzers on the market. The Discovery SA combines a high-sensitivity thermobalance, innovative humidity control chamber, and reliable autosampler. Innovative technology combined with our unparalleled reputation for service and support make TA Instruments the clear choice of scientists worldwide for vapor sorption studies.
