i need the informations about the all kinds of analytical as well as preparative columns those are available for HPLC, is there any site or links form where i can have all of these informations?

Go to www.waters.com and click on "Columns".

thank you for information

Also, click on the "FAQ" link near the upper left of the screen, and follow the links to "Additional information". That has web addresses for most of the manufacturers.

i'll be soon working with imipenem-cilastatin.
i read that conformers are formed of imipenem that causes the splitting of peaks.
which column 'll separate these conformers

i want to know which column 'll help to separate the cis and trans isomers of imipenem, as they are formed at their solution state
