No. The only way to keep the reaction from occuring is to keep them in an inert environment. If you put them in a sealed bag of argon or CO2 it will stop the reaction. The only problem with doing this is they need to be out in the air to start the reaction again for a few hours.
How long do you keep your sensors for?
The deterioration is linear, so I change mine every 12 months in Bernald. For example, if a new sensor can read 2.0 ppO2, they slowly read less and less, so after 12 months the maximum it can read may be 1.7. It may take 2-3 years to get to a point of not being able to read 1.0 (ie, 100% O2 at1 ata), so after I am finished with them, they are still useable in a sensor. If you get the right connector for your analyser, I will give you a constant stream of them.

JD make sure you charge the GUE twats........they have plenty of coin
