NOTE

Using an eluent generation setup (including a Dionex EGC) also requires the use of a Dionex CR-TC.

This section details the installation process for the continuously regenerated trap column. For a list of Dionex CR-TCs that are compatible with the system, see Continuously regenerated trap column (Dionex CR-TC).

Thermo Fisher Scientific service engineers can install the Dionex CR-TC during the initial system installation. Users can also install and/or replace the Dionex CR-TC.

Procedure

  1. To start, you will need the Dionex CR-TC and any tubing and connectors included in the ship kit, including the following items:
  2. 1/8-inch tubing with fittings/ferrules
  3. ¼-28 to 10-32 union
  4. PEEK tubing with fittings/ferrules
  5. Remove any packaging, including the shipping plugs on the Dionex CR-TC.
  6. Turn off and unplug the Dionex Inuvion IC System.
  7. Connect the PEEK tubing from the Dionex EGC outlet to the Dionex CR-TC ELUENT IN port.
  8. Connect the PEEK tubing to the ¼-28 to 10/32 union. Do not over-tighten the connection; a one-quarter turn of the wrench is adequate.
  9. Connect the ¼-inch tubing to the other end of the union.
  10. Connect the Dionex CR-TC ELUENT OUT to the Dionex CR-TC REGEN IN.
  11. Connect the Dionex CR-TC REGEN OUT to the long translucent tubing. This enables waste liquid to be directed into an adjacent waste beaker.
  12. From the Inuvion ePanel in Chromeleon CDS, turn on the analytical pump with the flow rate set at 1 mL/min. The pressure will increase; wait for 10 minutes.
  13. Turn off the analytical pump by selecting the Off button on the Inuvion ePanel; the pressure will drop.
  14. Disconnect and remove the REGEN OUT, REGEN IN, and ELUENT OUT tubing from the Dionex CR-TC. Do not disconnect the ELUENT IN port tubing.
  15. Mount the Dionex CR-TC on the mounting pins.
  16. Connect the REGEN OUT tubing and direct it to waste.
  17. Connect the Dionex CR-TC REGEN IN to the suppressor REGEN OUT tubing.
  18. Connect the Dionex CR-TC ELUENT OUT to the Dionex EGC degasser ELUENT IN tubing.
  19. Connect the Dionex CR-TC electronics cable to the CR-TC port on the Dionex Inuvion IC System.
