The correct use of an HPLC column is extremely important for the life time of a column and therefore for the benefit of your HPLC analysis. The following pages will give you some guidelines for the use, cleaning and storage of HPLC columns. These guidelines depend on the one hand on the nature of the chromatographic
To clean and regenerate a reversed phase column flush it with the following volumes of solvent. Reversed phase columns include silica, diol, nitro, and amino stationary phases. To clean and regenerate a normal phase column flush it with the following volumes of solvent.

HPLC COLUMN CLEANING PROCEDURES l (SILICA-BASED COLUMNS). The use of guard cartridges is recommended tor protection of HPLC columns from both lrit blockage and irreversible sample adsorption. However, over a period of time, columns may become contaminated by strongly adsorbed sample components
HPLC Column Cleaning And Regeneration. If adequate care is taken, it is possible to maintain column efficiency and reliability over an extended period of time. This document is intended to give information on the different procedures to help extend SiliaChrom® HPLC columns lifetime. This document will also cover column
ommitting buffers an salts. Use the cleaning routine that matches the properties of the column an what you believe is contaminating it. Flush columns with 20 column volumes (80 mL total for 4.6 x 250 mm column) of. HPLC-grade solvents. Run columns in reverse flow direction, with the outlet disconnected from the detector.
There are several resources that detail wash methods for HPLC columns. Knowing what might be clogging your column (step 1) will help you decide what to wash with. For instance, flush columns clogged with protein with urea, which denatures the protein and restores flow*. Check the column manual first, though—many
