Qubit Systems' S104 Differential O2 Analyzer (DOX) is the world's only patented differential oxygen analyzer with a resolution of ± 1 ppm O2 against a background of air. With the S104, researchers can measure real-time rates of respiratory oxygen consumption from tiny insects and photosynthetic oxygen production from intact leaves. When used with a CO2 analyzer 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. Because of its huge dynamic range, the S104 can also be used on a lower resolution setting to measure oxygen exchange in larger animals such as rats, rabbits and even pigs.

Features of the S104 include:

±1 ppm oxygen resolution against air (that's 0.0001%!)
Widest dynamic range of any oxygen analyzer
Easy calibration without special calibration gases
Separate analog signals for reference and sample pO2
Analog signals for differential pO2, absolute pressure, differential pressure, sample and reference cell temperature, instrument temperature
The DOX has the greatest dynamic range of any gas analyzer on the market. In true differential mode it has ranges of ±100, ±300 and ±1000 Pa O2. Both the reference and sample oxygen sensors are monitored independently at the same time. An automated Ref - Sample feature provides measurements of any oxygen difference. By choosing the appropriate range setting, oxygen exchange can be measured with any animal. The integrated calibration system uses ambient air and there is no need for costly cal gases. Calibration is quick, accurate and perfectly linear over the entire dynamic range of the analyzer. The S104 has been featured in several publications in top journals.

We recommend Qubit's C950 gas exchange software for use with the S104 DOX. The software calculates all major respirometry and photosynthesis parameters, and corrects data for variations in environmental conditions.
