Simultaneous multi-gas permeability measurements for O-rings, seals and mastics

The new Versaperm MS is a system for measuring the vapour permeability of O-rings, seals, coatings and mastics against virtually any gases or gas combinations – with just a single measurement.  Traditionally, individual systems would be needed to measure vapour permeability for each different gas.  

The vapour permeability of every seal is critical as, although most are great at keeping liquids out, many are virtually useless when it comes to vapours.  For example, seals made from materials such as silicone, cellulose, EVOH or PVOH allow water vapour to pass though almost as if they weren't there.  Vapours can then condense on the wrong side and cause all sorts of problems – from failed electronics to jammed equipment or rust.  Similar problems can occur with hydrocarbons, greases, oxygen and nearly any other gas.

Versaperm's introduction of a mass-spectroscopy based instrument helps overcome these problems and is accurate in the parts per million to parts per billion ranges. Where desired it can control temperature, pressure and other environmental factors.

The equipment can work on all seals, O-rings, mastics, coatings and clamping systems.  It works on samples or the seal material or the seals themselves and it can even work on entire systems, cases and enclosures.  This is critically important as manufacturing processes such as thermoforming, folding, moulding etc. may easily change vapour permeability by a factor of four.  The sealing process could affect it by an even greater amount.

The multi-chamber versions of the Versaperm MS allow measurements to be produced on several seals at the same time, different designs and clamping systems cater for varying sample types.

As well as manufacturing the instruments, Versaperm offers a technical consultancy service plus a permeability testing service for companies that need to test packaging or materials on an irregular basis.
