Package integrity instrumentation manufacturer Mocon is set to introduce three new accessories for its OpTech oxygen test system for food and pharmaceutical applications.

The technology uses an optical sensor that gives off light directly related to the amount of oxygen present in package headspace or dissolved oxygen in a liquid product.

The upgrades include a portability kit to enable mobile testing, the ability to test packages with little headspace such as blisters and food packages with limited headspace, and the new ImPULSE sensor.

Mocon vice president Doug Lindemann said by pairing the lightweight and ergonomic reader with a nine-inch tablet, users can test production line samples on the fly.

"The OpTech® oxygen test system has enjoyed significant success as a laboratory instrument, however our customers have expressed the need for a portable option," Lindemann said.

Besides production line usage, the instrument’s light weight and portability makes it suitable for package testing throughout the distribution chain to retail.

The company’s second new accessory for the OpTech reader is a needle attachment with fluorescing sensor material applied to its tip.

An accurate reading of oxygen concentration can be ascertained by inserting the needle into very small headspace packages, which cannot accommodate traditional testing methods.

Mocon will also unveil the new ImPULSE sensor, engineered to exclusively work with packages made out of opaque materials or retort packages.

A tack with the fluorescent sensor material punctures the package and adheres through a self-sealing adhesive.

In the process, a small hole is created when the package is punctured and oxygen from inside is exposed to the sensor that is sealed from the external environment.

From the transparent head of the tack, a reading is then taken allowing for measurements to be obtained over time to determine the longer term effects of oxygen in a package.

"Our new Op-Tech® capabilities are examples of our investment in technology that helps food and pharmaceutical companies engineer optimum packages for their applications," Lindemann added.
