Before assembling an ammonia or carbon dioxide ISE for the first time, or if reactivating after storage, the inner glass assembly should be conditioned and tested as a pH electrode. The pH buffer packets can be added to 50 mL of deionised or distilled water and the sensor assembly carefully immersed in solution. When the mV measurement in each buffer solution is stable and recorded, the mV difference can be calculated.
