Quality Control of Pharmaceutical Packaging

Gas Analyser Oxybaby Pharma


The O2/CO2 gas analyser Oxybaby® from Witt-Gasetechnik is a mobile measuring device for checking modified atmosphere packaging – peerless in the pharmaceutical and cosmetics industries. Thanks to its minimal gas sample requirement, the analyser is ideally suitable for small packaging, for instance the vials or blister packs typically used for medicines.

It takes just six seconds for the Oxybaby® 6.0 to reliably determine the oxygen content in packaging. The O2 value is displayed in 0.01% increments. The device only needs 2 ml of test gas to ascertain the residual oxygen content. This makes it the first choice for quality inspectors when it comes to determining the gas concentration in vials and blister packs. Such typically small packaging usually has only very limited free space, and only a small volume of gas. As well as oxygen content, the Oxybaby® 6.0 can optionally ascertain the CO2 concentration and calculate the nitrogen content.

The measurements are conducted randomly. To this end, the inspector pierces the packaging with the Oxybaby® needle and takes a sample at the press of a button. The results can be assigned to different product lines, products and users. The memory can hold up to several hundred entries. Data exports are possible at any time – an important function for complete documentation and certification. Witt naturally provides appropriate analysis software for this.

The durable oxygen sensor makes the Witt device especially economical. Another major advantage that is popular with users: The pump responds automatically to any blockages in the needle or filter and adjusts the output so that a correct measurement is ensured despite this. A warning message indicates serious blockages to the user. Further options include integrating a barcode reader for even faster operation or driving a printer via Bluetooth.

Modified atmosphere packaging is in widespread use today. Checking the gas composition in packaging is now normal quality assurance practice worldwide, the Oxybaby® having become established as the standard solution for such applications. Besides the pharmaceutical sector, the Oxybaby® has long been the industry-standard analyser for checking modified atmosphere packaging in the food industry.
