DO’s & DON’Ts For Column care to avoid/Minimize incidences
1.0 New HPLC Columns(Except Silica Columns for Normal Phase)
DO’s
- Before using the new column wash the column with water followed by an appropriate solvent mixture.
- For Silica Column for washing use solvent as Given in the Column Certificate.
DON’Ts
- Don’t saturate the new column directly with the mobile phase
- Don’t use water for washing of new Silica column.
2.0 Existing column ( Before Analysis)
DO’s
- Before analysis wash the column with water followed by the appropriate solvent mixture& then saturate the column with the mobile phase.
DON’Ts

- After analysis wash the column with the appropriate solvent mixture
- For long storage (more than 1 month) store the HPLC column in a pure organic solvent
DON’Ts
- Don’t store the column as it is without providing washing to the same.
- For long storage (more than 1 month) don’t store the HPLC column in the solvent mixture. (Organic solvent: Buffer solution)
4.0 Dedicated column
