Mocon OpTech O2 Model P Gas Analyser
Non-Destructive Headspace Oxygen Gas Analyser for Packages
For the fast and accurate analysis of the %O2 in headspace gas. In non-destructive mode, the OpTech O2 P is ideal for repeat shelf life testing of clear film packages. In invasive mode, it is ideal for testing packages with very small headspaces, such as coffee pods, or pharmaceutical blisters.
The OpTech O2 P has a flexible capability by using the optical fluorescence measuring principle. The accuracy of this method relies on the internal gas pressure of the test package being known and compensating for it. The unit does this automatically.
There are three ways the unit can be used:
Measuring headspace gas in clear film packages. A self-adhesive platinium sensor is adhered to the inside of the test pack before it is filled with product alone, or with both product and gas. The sticker sensor is placed in the package using a vacuum pen. After the package has been sealed, the oxygen content can be repeatedly measured by pointing the handheld reader at the sticker sensor. Ideal for shelf life studies.
Measuring the oxygen content inside opaque packages such as retort pouches. The ImPULSE platinum sensor – ideal for shelf and respiration trials. Complies with ASTM F2714-08 and ASTM F3136-15
Piercing packages when used in conjunction with the invasive needle that incorporates the platinum sensor. This test method is ideal for measuring packs with a limited volume of headspace gas such as pharmaceutical blisters. The fluorescence measuring method is not cross sensitive with CO2 so ideal for testing coffee pods.
Delivery includes PC software for data capture.
