IGAsorp Core
Dynamic Vapor Sorption Analyzer
Compact automated analyzer for essential DVS performance
The IGAsorp Core is designed for laboratories that need dependable DVS performance without the cost or complexity of a research-grade instrument. Built on the same proven engineering as the flagship IGAsorp systems, it delivers the accuracy required for routine moisture-sorption work while keeping operation simple and data quality consistently high. By focusing on the performance factors that matter most – stability, reliability, and ease of use – the Core offers a practical, high-value route into dynamic vapor sorption, which is ideal for teams with limited budgets or straightforward analytical needs.
To achieve this, the system combines highly stable temperature regulation with feedback-controlled humidity generation to maintain tightly defined sample conditions. An ultra-sensitive microbalance captures mass changes with high resolution across the full humidity and temperature range, while HIsorp software manages method setup, data capture, and analysis in a unified environment. Together, these components create a robust, reliable platform for generating trustworthy sorption data with minimal effort.
The IGAsorp Core uses an advanced temperature control module, the iSSB thermostat, for regulating the measurement chamber temperature between 15 and 40 °C. Developed by Hiden Isochema, the iSSB thermostat makes rapid and precise temperature adjustments to water held in a reservoir. This water is then recirculated through the isothermal measurement chamber housing the sample reactor, vapor generator and humidity sensor.

The well-proven split flow technique is used in conjunction with computerized feedback control to regulate humidity in the sample reactor. A rapid response relative humidity (RH) sensor and accurate flow controllers ensure exceptional performance from 0 to 98 %RH with 0.5 %RH overall accuracy. Sensor placement at the sample ensures true local humidity control.

Every IGAsorp uses a high precision microbalance engineered by Hiden Isochema to record sample mass changes as the environmental conditions change. Renowned for long-term stability and exceptional sensitivity, it enables detection of microgram-level weight changes. With balance temperature controlled separately from measurement temperature, you can trust every data point.
Low and high-mass balance options available.
