Vapour seepage in vehicles, especially fuel seepage, is heavily regulated worldwide.  Permeating vapour can cause all sorts of safety-critical and other problems when they get into the wrong places or out of the right ones.  Unfortunately water, air, fuel and greases all have the ability to permeate through the actual walls of any pipe, tank, seal, enclosure or material.  Temperature and pressure magnify the problem and getting things wrong can be disastrous.  

Versaperm has developed a fast new multi-chamber mass-spectroscopy based instrument that allows you to identify and correct problems by measuring permeability not just for water vapour, air and hydrocarbons but for virtually any other gas as well.  The system works on both complex components and assemblies as well as on flat material samples – actually it gives a better real-world result as it also measures changes made by manufacturing – which can easily reduce the permeability by a factor of four!

Versaperm's latest permeability mass spectrometer measurement system can determine this rate of flow (permeability) through the multiple materials used in the manufacture of cars, trains, trucks or any other vehicles.

Measurements can easily be correlated to international standards, but typically can be carried out significantly faster and more accurately due to the instrument-based techniques used by the equipment.

The equipment is fast, very accurate and typically gives results in the Parts Per Million (PPM) or Parts Per Billion (PPB) ranges for vapour/ material combinations.  Measurement can produced either on samples external to the instrument or internally in one of its chambers, depending on precisely what is being tested.

The system can give results in as little as 30 minutes for some materials, whereas conventional testing can take days or weeks and is usually less reliable.   Vapour can have a catastrophic effect on electronics and other systems and can even compromise the safety of the vehicle or system.  Measurement for certain automotive vapours is a legal requirement in most countries worldwide.

The equipment is computerised and extremely simple to operate requiring, at most, minimal training. 

Versaperm also offers a quick turnaround laboratory based permeability measurement and consultancy services for companies that need to test too few samples to make the purchase of equipment viable.
