Mass Spectrometer Sensors for permeability measurement

About Versaperm

Versaperm manufactures gas permeability testing equipment, offers a comprehensive permeability testing service and a materials consultancy. These are used to measure gas permeability and leakage, important in medical and pharmaceutical packaging, foils and films, coatings, food and confectionery packaging and contents, and many other applications.

Instruments

Versaperm designs and manufactures instruments to meet each customer’s needs. Instruments are typically be based on a modular MkVI design.

Testing Service

Our laboratory testing service has over 30 years experience to enable us to choose the best technique to measure your sample's permeability both quickly and accurately.

Applications

Permeability is often the most critial factor in a material or component's performance. It determines how drugs to loose potency, food goes off, how paper both prints and jams in equipment, how seals work and it can even cause electronics to fail.

Consultancy

Our Consultancy division combines our theoretical and practical Permeability skills in instrument design and manufacture. Permeability Consultancy

Mass Spectrometer Sensors

The mass spectrometry (MS) gas detection technique is an accurate and sensitive technique that can be used for any gas. It is based on ionizing a gas or vapour to generate charged molecules which are excited in an electromagnetic field to determine their mass to charge ratios and identify each component of the gas. The MS method is widely use due to its high precision and extreme versatility – though the equipment is comparatively expensive.

There are three main parts to a MS detector:-

An ion source, to ionize the gas - often an electron beam.
A mass analyzer, which applies an electromagnetic field. This separates the ions as different masses follow different paths.
A detector, which measures the abundances of each ion present.

Mass spectrometer

At Versaperm we are not tied to any specific sensor types or manufacturer and so we can always select exactly the right sensor for an application. Versaperm is a world technology leader in the measurement of gas permeability. We offer not only instruments but also comprehensive testing and consultancy services.
