The IGAsorp Core is ideal for laboratories needing reliable DVS performance, without the expense or complexity of a research-grade instrument. Built on the same proven engineering as the flagship IGAsorp systems, it gives the precision necessary for typical moisture sorption work while keeping operation easy and data quality consistent.
The IGAsorp Core vapor sorption system prioritizes stability, dependability, and ease of use, providing a practical and cost-effective solution.
The system uses consistent temperature regulation and feedback-controlled humidity generation to ensure precise sample conditions. An ultra-sensitive microbalance measures mass changes with high resolution across humidity and temperature ranges.
HIsorp software facilitates method setup, data acquisition, and analysis in a unified environment.
Together, these components constitute a strong and dependable platform that produces valid sorption data with minimum effort.

IGA Method
The IGAsorp uses the unique IGA method approach to calculate both sorption kinetics and equilibrium isotherms with high precision. By improving how equilibrium is found, the IGA method approach achieves high measurement accuracy, consistent findings, and faster measurement times.
Real-time kinetic analysis is performed by continuously monitoring weight-time data. The software analyzes this data and predicts the progress toward equilibrium, which is readily visible on-screen. Objective equilibrium criteria are automatically used to find the best place to proceed, assuring accurate and repeatable measurements.
