Use of gas exchange instruments in teaching

I apologize for cross-postings you may receive.
Last year I collected names of people who were using photosynthetic gas
exchange systems (IRGA-based) such as the Li-cor LI6400 in teaching. I
only found a couple of folks, so this has not been a very active group!!
I now realize that there are lots of people out there who are using the
Qubit O2 electrodes (or similar systems) in teaching. So I'd like to
reformulate the group to include such folks too. I met several people at
the ASPP meetings who have recently acquired the Qubit systems, and
exchanged a number of ideas. I also chatted with Steve Hunt from Qubit,
and picked up some good ideas.
If you'd like to be part of this group, send me your name. I'll try to
maintain the mailing list. Better yet, if you have some suggestions,
questions, lab exercises, etc., to share, send them along and I'll forward
them to the list.
To get things started - based on my own experience and talking to Steve
Hunt, I think using Phaseolus (kidney bean) in the Qubit system might not
be desirable (this is mostly anecdotal). Erratic and sometimes very low
rates are observed. At the meetings Steve was using soybean, which he has
found to be very reliable and robust.
