S104 DOX Differential O2 Analyzer

Qubit System's S104 Differential O2 Analyzer (DOX) is the world's only Patented Differential Oxygen Analyzer with a resolution of ±1ppm O2 against a background of air. With the S104 DOX, researchers can measure real-time rates of respiratory oxygen consumption from tiny insects and photosynthetic oxygen production from a single intact leaf. The S104 Differential O2 Analyzer has the greatest dynamic range of any gas analyzer on the market and on a lower resolution setting it can measure O2 exchange in larger animals, even Human.

When used with a CO2 Analyzer (S157) in an open gas exchange system, measurements of Gas Exchange Quotient allow non-invasive studies of respiratory metabolite determination and analyses of reductant flow in anabolic and catabolic reactions. S104 DOX O2 Analyzer can be employed in human metabolic studies using the room, pod or hood calorimetry approach.
