Troubleshooting and Maintenance Guide

Chromatographic Symptoms

Poor Peak Resolution

•

Set column flow to optimum linear velocity.

•

Install and use deactivated consumable parts in the inlet
(for example, a liner).

•

Perform column maintenance: Bake out contaminants,
replace the inlet guard column, and reverse and bake out the
column as needed.

•

Check column installation at both ends.

•

Select a higher resolution column.
