Semi-Permeable Membranes

Posted: Thursday 27th March 2014

Semi-permeable membranes and filters are used everywhere – from hi-tec equipment through to waterproof clothing and from cleaning up after oil spills to Kidney Dialysis, drinking water, coffee packaging and multiple industrial processes. However, measuring the effectiveness of these membranes can be difficult, costly and terribly time-consuming.

No More. Versaperm, a permeability technology leader, has launched a fast and accurate way for a company to measure the permeability of virtually any material, component for almost any gas in use today – including water vapour, hydrocarbons, oxygen carbon, dioxide etc.. Semi-permeable membrane filters are crucial in a wide range of industrial processes at temperatures that can vary up to and beyond 1000 C.

Versaperm’s permeability meter is highly automated and can cope with several samples at a time. It needs very little re-calibration and requires, at most, minimal training. Sensitivities depend on sensors, gasses and materials but are usually in the PPM (Parts Per Million) range, PPB for some materials. Results are both accurate and highly repeatable.

A range of sensors, based on a wide range of physical principals, enables Versaperm’s equipment to be used across an unprecedented variety of applications to characterise an ever expanding range of materials, compounds, containers, products and laminates. Temperatures can range up to around to around 1100 C.

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