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 From walkerdavi from googlemail.com Sat Jun 20 00:19:14 2009 From: walkerdavi from googlemail.com (David Walker) Date: Sat Jun 20 02:33:21 2009 Subject: [Photosynthesis] re measurement of oxygen Message-ID: The use of the oxygen electrode for this purpose may be downloaded from http://www.shef.ac.uk/library/libdocs/use.pdf -- >From David Alan Walker, FRS Emeritus Professor of Photosynthesis University of Sheffield, U.K. -------------- next part -------------- An HTML attachment was scrubbed...
