Dear Colleagues,
   Good afternoon. We are trying to perform a photosynthesis
experiment that requires us to directly measure O2 production levels
from leaves. Our equipment only allows us to measure O2 concentrations
greater than 50 ppm, but we need a more sensitive sensor that allows
for measurements less 50ppm.
  Could you advise us on how to proceed on obtaining such a sensor?
Thank you,
Stephane & Ronex
