front side of the monitor.
Integrate the pH monitor into the FPLC/HPLC flow path by installing it
down stream of the conductivity monitor. You can do this by mounting
the pH monitor onto the AZURA® Organizer, which is placed on the
AZURA® Click (both sold separately) at the side of the system. For more
information see supplement “ AZURA® Organizer (V6868) “.
Note:
