Permeability leader Versaperm has introduced a new version of its technology-leading permeability meter which can be configured to measure permeability for gases including water vapour, helium, hydrogen, hydrocarbons, solvents, oxygen, carbon dioxide and most other gases. The equipment includes new and highly sensitive ranges of sensors, improved computer control and both single and multiple chamber options.

Today, laboratories have to characterise and measure an ever expanding range of materials, compounds, containers and laminates in the never-ending search for new technical and marketing features.   

Permeability is vital in real-world applications as it dramatically affects characteristics from the shelf life of pharmaceuticals and foodstuffs, through to handle-ability and even the quality of the printing.  Manufacturing processes including heating, forming and bending can quickly change permeability by a factor of 4!  This means the results for most products simply can’t be estimated from the constituent material’s properties but must be measured directly. 

Versaperm’s new permeability meter is highly automated and its computerised control can cope with several samples at a time - and still produce a permeability measurement in as little as 30 minutes for some materials.  It needs very little re-calibration and requires, at most, minimal training to give results that can be accurate to better than one part per million. Sensitivities depend on sensors and materials but are often in the PPM range, PPB for some materials. Results are both accurate and highly repeatable.

Versaperm also offers a consultancy service for laboratories that need to measure permeability of complex new materials and assemblages.
