As the Spring Festival holiday is approaching, before the end of the work, everyone should do a good job of maintaining the ion chromatograph so that the instrument can be used normally in the coming year.

1. Chromatographic column

Before shutting down, flush the chromatographic column according to the conditions of the last experiment, and then pass the solution of the specified concentration according to the storage conditions on the chromatographic column specification, and remove the two ends and seal for storage.
2. Suppressor, advection pump and flow path system
Online flushing: remove the chromatographic column and seal it well;
Use two-way to replace the chromatographic column and connect the pipeline;
Turn off the suppressor power switch;
Replace the eluent with ultrapure water and set a flow rate of 1.0 mL/min for 30 minutes.
3. Normal shutdown



(To prevent crystallization and damage to the instrument, please follow the above steps to shut down.)
