Depending on the specific components in the system (such as an analytical column, conductivity cell, and back pressure coils), ¼-28 or 10-32 ferrule/bolt liquid lines may be required. All necessary tubing and fittings are supplied in the detector, or Dionex RFC-10, or Dionex RFC-30 Ship Kits. To purchase or assemble ¼-28 or 10-32 ferrule/bolt liquid lines, refer to, “Dionex Liquid Line Fittings.” Always use 0.005” i.d. PEEK tubing with 10-32 ferrule/bolt fittings on 2 mm systems. When possible, use 0.010” i.d. PEEK tubing with 10-32 ferrule/bolt fittings on 4 mm systems. Avoid adding dead volume to the system by keeping all eluent lines as short as possible.
Procedure
- Install the Dionex DRS 600, Dionex ERS 500e or Dionex AERS 500 Carbonate in the first slot inside the Chromatography Module.
- Connect the outlet of the analytical column to the ELUENT IN of the suppressor.
- Connect the ELUENT OUT port of the suppressor to the inlet of the conductivity cell.
- Install a waste line from the conductivity cell that generates 30 – 40 psi (carbonate eluents) or 10 – 40 psi (other eluents) of back pressure at the flow rate required by the application. Use the appropriate i.d. tubing depending on your application requirements. See Assemble back pressure coils for the correct back pressure tubing requirements.
Install and adjust the flow rate of water from the pressurized water delivery system to the regenerant chambers of the suppressor (see the table in Regenerant flow path connections in the AutoSuppression External Water Mode).
