Columns Agilent compatible

For the Prevail Organic Acid column, I attached here the link to the Hi-Plex column compendium (https://www.agilent.com/cs/library/applications/5990-8801EN%20Hi-Plex%20Compendium.pdf )

For the Restek Ultra Aq, I used the column comparison database at HPLC Columns - HPLC column selectivity measurements of more than 600 reversed phase columns from over 30 manufacturers . I did not find an Agilent column which displays identical selectivity (as defined by an Fs value < 3). The closest comparison would be Poroshell 120 SB-C18 with an Fs value of 10.40. I attached here an LCGC article where John Dolan & Lloyd Snyder talk about the Hydrophobic Subtraction Model and how to interpret the Fs value. Happy reading :-)....

Others with hands-on experience with both of the columns you list might point you in a more specific direction.

Many thanks,

Danny

The Prevail Organic Acid column is a polar embedded C18  column, for this we have multiple alternatives:

• Poroshell 120 SB-Aq
• ZORBAX SB-Aq
• Polaris C18-A 

HiPLex columns can be another choice.

Our alternatives for the Ultra Aqueous C18 are not so close, but the same list as above.

Without knowing more about an application it's difficult to give good advice.

Dear, always very grateful for your excellent and clarifying responses.
These columns are for lactic acid detection.
