DESCRIPTION
An optional pH valve with an integrated pH electrode (ordered separately) to monitor pH gradients and elution conditions in-line.
pH monitor is easily calibrated by injection of calibration buffer directly into the valve with the pH electrode mounted.
A flow restrictor is connected to the pH valve and can be automatically included in the flow path to generate a back pressure that prevents the formation of air bubbles in the UV flow cell.
Bypass enable the pH electrode to be stored and kept in place on the valve at all times.
Note that pH electrode 28-9542-15 needs to be ordered separately.
