No, it is base treated, therefore acidic compounds will be adsorbed by the base treatment, resulting is peak tailing.

What does DB stand for in Supelcosil LC-8DB HPLC column, Product 58354?
1 answer-
DB stands for "deactivated base", and refers to the base treatment of the packing in this column. Without this treatment, basic compounds will adsorb to active acidic silanol sites. If starting a new method, Supelco suggests using a new-technology/pure-silica C8, such as the Ascentis C8.
