O2 / CO2 Analyzers & Packaging
O2 and CO2 analyzers for quality control. Oxygen and carbon dioxide analyzers, BPA detection and package leak detectors from Quantek Instruments.
Comparison of O₂ / CO₂ Analyzers and Package Testing Equipment
| INSTRUMENT TYPE | BEST SUITED FOR | WHAT IT TESTS | KEY ADVANTAGE | KEY CONSIDERATION |
|---|---|---|---|---|
| Portable O₂ / CO₂ Analyzer | Production-line checks and verification of modified-atmosphere packaging | O₂, CO₂ or both depending on configuration | Allows measurements to be performed directly at different points in the production process | Gas to be measured, measurement range, sample volume and testing frequency |
| Benchtop O₂ / CO₂ Analyzer | Laboratories and quality-control operations performing regular headspace gas analysis | O₂, CO₂ or both depending on the model | Fixed configuration suited to repetitive analysis and data management | Required gases, sampling method, measurement range and documentation needs |
| Vacuum Leak Tester | Detecting leaks in flexible packages and other sealed containers | Package integrity through vacuum testing and observation of leakage | Helps identify sealing defects that may compromise product protection | Package type and dimensions, test method and applicable standards |
| Digital / Automated Leak Testing System | Quality control requiring more controlled and repeatable package-integrity testing | Package sealing and integrity according to the system configuration and test method | Improves control and repeatability of test parameters | Level of automation, package type, test method and validation requirements |
| BPA Detection Test | Bisphenol A analysis in applications requiring selective preparation before instrumental analysis | Bisphenol A (BPA) | Selectively isolates BPA before analysis by HPLC, UPLC or LC-MS | Analytical method, sample preparation and target concentration range |
Did You Know?
Gas analysis and package integrity testing play an important role in the quality control of packaged foods. Oxygen (O2) and carbon dioxide (CO2) analyzers can be used to verify the gas composition inside a package, while leak testers help detect defects that may compromise package integrity. These controls are particularly relevant for products packaged under modified atmosphere.
Why measure O2 and CO2 inside food packaging?
In modified atmosphere packaging, oxygen and carbon dioxide concentrations should correspond to the conditions established for the product. Measuring these gases helps verify the packaging process and identify variations that may result from packaging conditions, leakage or other changes affecting the internal atmosphere.
What is the difference between a portable gas analyzer and a benchtop model?
A portable analyzer facilitates testing at different locations within a facility or near a production line. A benchtop instrument is better suited to a fixed testing station and routine laboratory or quality-control measurements. The appropriate choice depends on testing frequency, working environment and the gases that need to be measured.
What tests can complement O2/CO2 package analysis?
Gas composition analysis can be complemented by package integrity and leak testing. Depending on the product and packaging material, additional tests may also be required. Combining different testing methods allows quality-control personnel to evaluate both the conditions inside the package and its physical integrity.
