If the column was properly flushed after use and stored in 100% organic solvent such as acetonitrile, the column will survive for many years.

5.6 Discard of HPLC / GC column 1 Discard the column if it is not meeting the criteria of Tailing factor, theoretical plates, Resolution, Fronting, Splitting/ damage etc. 5.6. 3 Discarded columns shall be kept separately and affixed to the label as ?Discarded column-Do not Use?.

Cleaning HPLC Columns The cleaning procedure typically involves using an isocratic/gradient wash that is closest to the last solvent system on the column , but replacing the buffer with HPLC grade water. This will ensure that the buffer components are removed from the column.

Symptoms of deterioration are poor peak shape, split peaks, shoulders, loss of resolution, decreased retention times, and high back pressure. These symptoms indicate contaminants have accumulated on the frit or column inlet, or there are voids, channels, or a depression in the packing bed.

An HPLC column has a finite lifetime. It is recommended that you routinely monitor a column's retention characteristic and performance using standards.
