I suspect that to test photolysis of water one can use our ( Columbus
Instruments) O2/CO2 Respirometer which has sensitivity of 0.2 uLO2 /h .
Description follows:

Universal O2/CO2 Respirometer

New respirometer is intended for testing and modeling in the laboratory
gas exchanges during aerobic or anaerobic biodegradation/bioremediation.It

can also be used to measure respiration of alga,fungi,
bacterial response to antybiotics and toxins, respiration of soil  etc.
Up to 80 sample chambers ( variety of sizes)  can be connected to
Respirometer which is equipped with O2 and CO2, analyzers
.Optional CH4 and H2S, H2 are also avilable.  Sample
chambers can be refreshed from the compress gas bottles or
from the Columbus Instruments programmable gas blender.
Respirometer is capable to measure head space gas
exchanges on 24h basis. Multiple experiments of different
length can be conducted in the same time using liquid or
solid samples.
Due to the exceptionally high sensitivity 0.2 uL of gas /h,
Bioremediation Respirometer can monitor very slow
biodegradation processes of plastics, hydrocarbons,
explosives, creozote as well as respiration of insects, aquatic plants and
