CO2 Permeation and Sorption Testing

A patented, rapid, accurate, and reliable method for measuring CO2 permeation and sorption in packaging materials.

  • Results in hours for most packages
  • Nondestructive testing.
  • Direct and accurate measurement of CO2 efflux from packages.
  • Statistically robust shelf-life predictions with built-in ANOVA engine and confidence limits calculations.
  • Test bottles, closures, films, or whole packages.
  • Test at precisely controlled temperature and humidity conditions.
  • Easy to use graphical interface requires no operator training

Coventional methods for measuring CO2 permeability in packages essentially measure changes occurring in the package CO2 content during a simulated shelf-life test. Such tests are inherently slow because it takes a long time to see a measurable change in CO2 content. Also inherent in such methods is the challenge of having to measure very small changes (often less than 10%) in package CO2 levels accurately over extended time periods. Further, since these tests take so long to complete they are also of little use in predicting shelf life of a packaged batch of product.

QuantiPerm CO2 Permeation – Model 504 Advantages

  • Absolute shelf life characterization now posible
  • Save months of measurement time compared to conventional test methods
  • Expect significant cost savings compared to conventional methods
  • Highly stable, and sensitive sensor based on infrared absorption
  • Self-integrating operation over multiple cycles for accurate measurements
  • Solid-state (peltier) temperature control
  • Accurate relative humidity control
  • Small footprint
  • Sensor calibration is NIST traceable–certificates available

Principle of operation: CO2 emitted by packages under controlled environmental conditions (temperature, humidity) is directly measured with a highly sensitive infrared absorption sensor. Self-integrating operation over multiple cycles allows the determination of accurate permeation rates in a statistically rigorous manner. The sensor is also extremely stable and requires calibration only once in a year!

User Interface: Intuitive and user-friendly graphical interface requires little or no training to operate the instrument.

Specifications: Self-integrating system allows virtually unlimited measurement range and accuracy, from as little as 50 mL/pkg/day to greater than 3 L/pkg/day. Accuracy: better than 5% of reading. Built-in ANOVA engine is part of the data analysis routine, and results are reported with confidence intervals at chosen levels of significance. Temperature Control range: From 200 F (100 C) below ambient to 1200 F (500 C). Better than ± 0.10 F (± 0.050 C) control stability at the measurement sensor.

Determine shelf-life of your packages!

Customer Testimonials

What are our clients are saying about us?

Matt Sebastionelli, Craftpack Bev.

We have QuantiPerm’s xFlow systems for both carbonation and deoxygenation applications. They work beautifully and proved to be a very robust solution for our beverage business. The folks at QuantiPerm are super friendly and always eager to help, and technically extremely competent

Benjamin Schottle, Phillips Brewing Co.

We are very happy with the H2Odeox deoxygenation unit we bought from Quantiperm. It was easy to install, it’s easy to use, and it performs well. It delivers water under 30 PPB minutes after startup and doesn’t take up much space, which is important to us. A low flowrate of CO2 across a high surface area membrane, contained inside a couple of compact canisters, draws O2 out of the water in a surprisingly efficient manner.
