The Dionex DRS 600, Dionex ERS 500e, and Dionex AERS 500 Carbonate are installed in the column or detector chamber of the chromatography module right after the analytical column and before the conductivity detector cell.

The mounting location varies depending on the IC system:

  • Dionex ICS-6000: Suppressor mounts on the conductivity detector module in the DC.
  • Dionex Integrion: Suppressor mounts on the conductivity detector module in the detector compartment.
  • Dionex Aquion: Suppressor mounts on the component panel behind the front door.

Refer to the Dionex IC System Operator’s Manual for further details.

Procedure

  1. Orient the suppressor with the ELUENT IN port and the cable at the top if installed vertically; align the slots on the back of the suppressor with the tabs on the panel.
  2. Press in, and then down to lock the suppressor in place.
  3. Lift up and pull out to remove the suppressor.
  4. Ensure the suppressor is plumbed properly according to the selected mode of operation.

Refer to Installation for complete installation instructions.

WARNING

Keep the regenerant chambers full with the appropriate regenerant solution or water. The membranes and screens in the Dionex DRS 600, Dionex ERS 500e, or Dionex AERS 500 Carbonate must be completely hydrated to maintain liquid seals and chromatographic performance.

CAUTION

The correct amount of back pressure on the conductivity detector for optimum operation is 40 psi for carbonate eluents; less for RFIC hydroxide and MSA eluents. Connect the back-pressure coil(s) appropriate for your column i.d. and flow rate. Back pressures over 450 psi after the Dionex DRS 600, Dionex ERS 500e, or Dionex AERS 500 Carbonate can cause irreversible damage.

CAUTION

Do not cap the waste reservoir.

DANGER

The Dionex DRS 600, Dionex ERS 500e, and Dionex AERS 500 Carbonate generate 24 mL of hydrogen gas per hour at 50 mA; this level is not dangerous unless the gas is trapped in a closed container and allowed to accumulate. The gas separator waste tube must be open to the atmosphere, and not in a confined space, to operate properly.
