Good chromatography isn’t just about when the pumps are running. Taking care of your column when not in use is important for lifetime and reproducible performance. When shelving a column, be sure to flush out any buffers or other additives. You can use a solvent mix similar to initial run conditions, just without additives, and that can be good for a couple days of storage. For longer term storage, you should choose a storage solvent appropriate to your column and method. And always make sure to document the date and storage solvent, so you have the information you need to get back up and running as soon as possible.
