MOCON, Inc., the world’s leading manufacturer of permeation instrumentation, has developed a new oxygen transmission rate test instrument which accurately and repeatably measures barriers to 5x10-4cc/(m2 x day), ten times lower than previous levels. The OX-TRAN® Model 2/21 10x system measures films or packages at precise temperature and relative humidity conditions. Learn More...
Important Factors in Permeation Testing

WHAT IS PERMEATION?
Graham’s Colloidal Diffusion illustrates the three-step process of permeation through a material. The first step is the sorption of the permeant into the material. Next, the permeant diffuses through the material followed by the final step where it is desorbed from the other side. This entire process is driven by a concentration difference or gradient. Molecules will permeate from the high concentration side of the material to the low concentration side. This will continue until both sides are at equal concentration levels. Learn More...
A new standard in Oxygen Analysis

The OpTech-O²-Platinum is a non-destructive Oxygen analysis device with 3 test modes for measuring headspace O², dissolved O² in a liquid and barrier film O² permeation properties.
Because the sensor does not consume any gas, measurements can be repeated on the same pack to create an O² v Time profile over the product shelf life. Applications include modified atmosphere food packaging, beverage containers, and pharma/medical packs, in both R&D and QC environments.
- Quality Control checks of MAP packs, single value or time profile
- For liquid contents, measure headspace O² and dissolved O²
- O² permeation rate of packages & films, including porous & perforated films
- Very small headspace volume packs, and vacuum packs
- Determine shelf life for an Oxygen sensitive product
Physical Testing of Medical Packaging

Ed Emerson, Business Development Manager at Mocon Medical Packaging Group, discusses the challenges of maintaining a 'sterile barrier system' over a products entire shelf life.
Responsibility for maintaining safety and sterility is shared by development engineers, packaging developers, packaging managers, product managers, and quality auditors. A traditional way of testing a package’s sterile barrier system at any point in its life has been to bathe it in a contaminated solution and then test by culturing the contents to be sure that microbes have not penetrated the package. While workable, this microbial challenge testing has several drawbacks. Learn More...
MOCON UNVEILS WVTR INSTRUMENT FOR ULTRA-HIGH BARRIER FILMS WITH GREATER SENSITIVITY
Posted on 25/03/2013

MOCON, Inc., the world’s leading manufacturer of permeation and package integrity instrumentation, is launching a new system to measure the water vapour transmission rate (WVTR) of ultra-high barrier films with greater sensitivity than ever before possible.
The new generation AQUATRAN® Model 2 WVTR measurement instrument targets commercial or developmental ultra-high barrier structures for flexible films in organic light-emitting display (OLED), solar and similar demanding applications, which require accurate and extremely sensitive instrumentation tobuild performance statistics.
The AQUATRAN® Model 2 uses proprietary technology to accurately and repeatably measure WVTR down to 5 x 10 -5 g/m 2/ day. This is one order of magnitude lower than its very successful predecessor the Model 1 which was launched in 2005. The Model 2 uses propriety technology to increase sensor sensitivity and reduce the possibility of ambient humidity interfering with test results. Further, the AQUATRAN® Model 2 is the only system available for measuring trace WVTR that is not calibration dependent, providing more accurate and repeatable results than calibration dependent methods.
The AQUATRAN Model 2 utilizes MOCON’s newest AquaTrace® Gold coulometric longer-life sensor which is based on Faraday’s Law.Every water molecule entering the sensor is directly converted to a measureable charge. No calibration is necessary, assuring an accurate test result. Transient data also is quantifiable and can be viewed during or after the test. (Analysis of transient data can yield important information about an OLED structure such as detecting defects and voids in the applied coatings.)
Additional enhancements to the AQUATRAN® Model 2 include improved electronics; enhanced block and valve design, and the introduction of Tru-Seal technology which reduces seal edge leaks due to ambient humidity. The AQUATRAN® Model 2 is available in two versions.The G system operates between 35 and 90 % relative humidity (RH) and a temperature range of 10 to 40 °C. The W version offers 100 % RH and a temperature range 10 to 50 °C.
