Installing the Trap Column for KOH-Based Separations
Installation of a Thermo Scientific Dionex ASTC 500 Anion Trap Column
(P/N 085359) is recommended for all KOH-based separations performed on
capillary systems. The Dionex ASTC 500 trap column removes trace
contaminants from deionized water. Install the trap column between the pump
pulse damper and the Dionex EGC inlet.
1. Locate the trap column and the trap column tubing assembly
(P/N 078497) in the IC Cube Ship Kit (P/N 072003).
2. Connect one end of the Dionex ASTC 500 tubing assembly (P/N 078497)
to the pulse damper outlet (see
) and connect the other end to
the trap column inlet.
3. (Optional) Connect a temporary waste line to the outlet of the trap
column. Use the
TO CR-TC REGEN OUT
line, which is part of the pre-
assembled tubing chain.
4. Set the pump
Purge
flow rate to 2.0 mL/min and the

. Do not open the purge valve (you can cancel the Ready
Check message that appears). The trap column is flushed for 30 minutes.
NOTE
When flushing is complete, there should be no bubbles
present and the effluent should be colorless.
5. On the pre-assembled tubing chain (see
), connect the black
PEEK tubing labeled
TO PUMP/DAMPER
to the outlet of the trap column.
Keep the remaining tubing in the chain connected.
