Electrochemical flow cells

Answer

Three reference electrodes are available:

  1. salt bridge Ag/AgCl  –  traditional best known REF. Separate REF chamber, compatible with most conditions.
  2. in situ Ag/AgCl (ISAAC)  –  convenient alternative, requires 2 mmol/L chloride ions in mobile phase.
  3. HyREF reference electrode  –  robust, maintenance free, compatible with harsh conditions

For different application areas see flow cell manuals and Application notes.
