This graph is from a study investigating the day to day retention time precision with two test solutes on the Cogent Diamond Hydride 2.o™ HPLC column

Peaks:
Blue Trace: Phenylalanine
Red Trace: Phenylglycine

Many factors can affect column robustness and lifetime, so it is not possible to define specific values for those parameters.
