Product Overview

The IGA-002 gravimetric analyser allows vapour sorption in addition to the gas sorption features of the IGA-001 . The IGA design integrates precise computer-control and measurement of mass change, pressure and temperature to enable fully automatic and reproducible determination of gas and vapour sorption-desorption isotherms and isobars in diverse operating conditions.

Anti-condensation protection to 50 ºC is incorporated in the IGA-002, which allows operation with water and an extensive range of hydrocarbon vapours. Additionally, a range of sample environment options are available to allow operation at temperatures from -196 to 1000 °C and at pressures ranging from ultra-high vacuum to 20 bar. The IGA-002 has been used to study water and hydrocarbon vapour sorption on a wide range of materials, including pharmaceuticals, carbons, catalysts, zeolites, clays and polymers.

Product Applications

Typical IGA-002 application areas include:

• Packaging
• Polymers
• Moisture sorption
• Organic vapour sorption
• Pore size determination
• Vapour diffusion coefficient determination

The IGA-002 has been used to study the sorption of a wide range of gases and vapors, including:

• Alcohols (e.g. butanol, ethanol, isopropyl alcohol, methanol, propanol)
• Aromatics (e.g. benzene, styrene, toluene, xylene)
• Chlorinated compounds (e.g. chloroanisole, chlorobenzene, chloroform, chlorotoluene, cyclohexane)
• Hydrocarbons (e.g. butane, ethene, hexane, octane)
• Unreactive probe gases (e.g. nitrogen, argon, carbon dioxide)
• Reactive species (e.g. hydrogen, oxygen, carbon monoxide, methane)
• Water
