Pump trap column installation and regeneration

Task

Description

Install the Dionex IonPac ATC-HC Trap Column

The Dionex IonPac ATC-HC Trap Column (Item # 059604) is used to trap anions that may be in the carrier solution that could result in high blanks. The Dionex IonPac ATC-HC should be regenerated prior to installation.

Regenerate the Dionex IonPac ATC-HC Trap Column

Using a pump other than the carrier pump, the Dionex IonPac ATC-HC should be regenerated and rinsed:

Procedure

  1. Regenerate the Dionex IonPac ATC-HC with 0.5 M NaOH for 50 minutes at a flow rate of 1 mL/min.
  2. Rinse the Dionex IonPac ATC-HC with deionized water for 30 minutes at a flow rate of 1 mL/min. If the carrier solution is different from water, equilibrate it to the carrier solution for 30 minutes at a flow rate of 1 mL/min.

Install the Dionex IonPac CTC-1 Trap Column

The Dionex IonPac CTC-1 Trap Column (Item # 040192) is used to trap cations that may be in the carrier solution that could result in high blanks. The Dionex IonPac CTC-1 should be regenerated prior to installation.

Regenerate the Dionex IonPac CTC-1 Trap Column

Using a pump other than the carrier pump, the Dionex IonPac CTC-1 should be regenerated and rinsed:

Procedure

  1. Regenerate the Dionex IonPac CTC-1 with 0.5 M H2SO4 for 50 minutes at a flow rate of 1 mL/min.
  2. Rinse the Dionex IonPac CTC-1 with deionized water for 30 minutes at a flow rate of 1 mL/min. If the carrier solution is different from water, equilibrate it to the carrier solution for 30 minutes at a flow rate of 1 mL/min.
