CALIBRATION
Calibration is done with two standard gases bubbled through a liquid. Typically 5% and 10% CO2 balanced Nitrogen. The probe responds slugishly to low CO2 levels, so to help with repsonse time, the amount of exposure to ambient should be limited in use.
CLEANING
Using any electrode in solutions containing protein requires the electrode be rinsed with an enzyme cleaning solution.
After each use, we recommend cleaning our electrodes with Terg-a-zyme (Alconox, Inc.) solution by submerging the electrodes for a couple of minutes in order to remove all protein from the glass and reference junction.
This will prolong the useful life of the electrodes.
STORAGE
Always clean the microelectrode before storing:
- Long-term (over 2 weeks): Rinse probe and keep membnrane attached to prtoect the glass tip
