IGA-002 Gravimetric Vapor Sorption Analyzer

IGA-002

SINGLE COMPONENT GRAVIMETRIC ANALYZER, FOR PRECISE CHARACTERIZATION OF GAS & VAPOR SORPTION EQUILIBRIA & KINETICS

BENEFITS OF IGA-002

Unrivalled measurement precision, accuracy and repeatability
Unparalled vapor pressure control and measurement resolution
Fast and accurate analysis of equilibria and kinetics using the IGA method

INTRODUCING IGA-002

The IGA-002 is a high resolution vapor sorption analyzer for precisely characterizing vapor-solid interactions. Compatible with an extensive range of vapors, the IGA-002 also offers the full gas sorption capability of the IGA-001, measuring changes in sample mass as a function of temperature and pressure. The unique IGA method analyzes real time gravimetric data to determine kinetic parameters and simultaneously predict sorption equilibrium.

KEY FEATURES

Suitable for use with a wide range of gases, vapors, materials and methods
Active vapor pressure regulation from 10^-3 mbar
Built-in anti-condensation protection to 50 °C
Sample temperature stability and accuracy of ± 0.02 °C
Unrivalled long term stability and continuous weight measurement
Advanced kinetic analysis for sorption rate and diffusion coefficient determination

THE IGA METHOD

Hiden Isochema’s unique IGA method is applied independently to every step in a gravimetric sorption measurement. At each step, the pressure and temperature are actively regulated, with resultant changes in sample weight continuously recorded.

The kinetic weight data is analyzed in real-time, and the trend toward equilibrium is predicted and displayed on screen. Equilibration criteria are applied to objectively determine the period allowed before the measurement moves on to the next pressure or temperature value. Each equilibrium point is plotted on an isotherm or isobar, and the full raw data is also recorded.

The IGA method therefore allows consistent analysis with optimum measurement accuracy and faster overall process times.

APPLICATIONS

IGA analyzers are widely regarded as the benchmark for gravimetric sorption analyzers and are used in an extensive range of applications:

Moisture and organic vapor sorption
Diffusion coefficient determination
Thermodynamic and kinetic studies
Gas sorption capacity determination

IGA instruments are used in both academic and industrial laboratories globally and are continuously producing high precision reproducible data. The IGA’s reputation is underpinned by publication of data in over 700 peer reviewed papers, including many in high profile journals.
