Dynamic Vapor Sorption Analyzer

Compact Automated Analyzer for Essential DVS Performance

Benefits of IGAsorp Core
  • Unrivalled environmental control and weighing performance for entry level DVS
  • Guided workflows and effortless operation with HIsorp software
  • Proven reliability supported by 3-year warranty and guaranteed lifetime support
Introducing IGAsorp Core

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.

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.

Key Features
  • Designed for essential water sorption studies
  • Unrivalled temperature stability from 15–40 °C, powered by the compact, high‑performance iSSB thermostat
  • Fast response RH sensor and high-precision flow control for accurate humidity regulation
  • Temperature and humidity measured directly at the sample for true environmental accuracy
  • An ultra-sensitive, independently thermostatted microbalance for exceptional long-term stability
  • HIsorp software streamlines workflows with guided methods, automatic reporting, and integrated analysis
  • Unique IGA method for endpoint determination delivers high measurement accuracy and shorter experiment durations
  • Built‑in conformance tests for weight, temperature, and humidity verification
  • Optional 21 CFR Part 11 compliant mode with three user privilege levels for secure, regulated operations
IGA Method

The IGAsorp employs the unique IGA method to determine both sorption kinetics and equilibrium isotherms with exceptional accuracy. By optimizing how equilibrium is detected, the IGA method delivers high measurement accuracy, consistent results, and shorter measurement durations.

 

Real-time kinetic analysis is achieved through continuous monitoring of weight-time data. The software models this data and predicts the trend toward equilibrium, which is clearly displayed on-screen. Objective equilibrium criteria are automatically applied to determine the optimal point to proceed – ensuring reliable, repeatable measurements.
