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 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

CO2 permeation: 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.
