Measuring  basal metabolism of obese mice/rats

We at Columbus Instruments developed very precise system ( open flow
indirect calorimeter- "Oxymax") which measures VO2/VCO2 of genetically
defective animals  either is home cages or during exercise. We utilize
differential measurement of % O2 and %CO2  between input and output of
animal chambers with very high resolution gas analyzers (0.001%). 
Optional simultaneous measurements of animal activity and food intake is
also possible. This system already helps researchers in major
pharmaceutical companies from Amgen, through Merck to Sandoz and Zeneca.
If you like to receive more information with detailed system description
and application papers, let me know by  providing street address to :
