Breakthrough Luminescence Technology for Measurement of Dissolved Oxygen (read more)

Dissolved oxygen in a liquid stream can have many negative impacts on processes because it causes corrosion and oxidizes materials, such as piping and boilers. Liqui-Cel® Contactors are an easy-to-operate, modular solution for degassing without using chemicals and without investing in large vacuum towers or outdated forced draft technology. (read more)

Mettler-Toledo Thornton announces the release of a new high-performance dissolved oxygen sensor for ppb measurements in the power and semiconductor industries. Featuring especially fast downscale response of 98% in 90 seconds, it is ideal for cycling power plants where dissolved oxygen levels change... (read more)

The RedEye^TM is a revolutionary oxygen sensing product designed specifically to measure oxygen in packaging. The RedEye^TM is integrated into the inside of the package during the packaging manufacturing process and when used with a blue LED and fluorometer, will quantitatively report the amount of oxygen in the package.

Thornton's highly reliable dissolved ozone measurement capability uses a proven sensor design with rapid and accurate response to ozone concentrations. At the low end, its excellent sensitivity gives positive detection of zero ozone after destruction by UV light. (read more)

The Aanderaa Oxygen Optodes are based on the ability of selected substances to act as dynamic fluorescence quenchers. The fluorescent indicator is a special platinum porphyrin complex embedded in a gas permeable foil that is exposed to the surrounding water.

In this case oxygen is the fluorescence quencher. This technique allows for oxygen measurements with minimal maintenance. (read more)
