Thanks for the input!

Oldest column I have run is probably 5-6 years in storage, popped it on the system and conditioned as per our usual procedures and was absolutely fine for another year or so of heavy analysis. I would say that if it's unopened and not been abused in a lab for the last 10 years you would be fine but unfortunately the only way to know for certain is to buy the column and run some kind of system suitability test on it.
Nowhere in any of the waters literature I can find says columns have a lifetime expiry so fingers crossed.
Out of interest what was wrong with the column you bought? Can you do some method conversion to make it suitable?
Good luck and all the best,

I am finding a column on eBay that is brand new/sealed packaging but it is 10+ years old. It is a Waters Amino (NH2) Column.
