Opis ogólny
SUPELCOSIL LC-DB phases are specially deactivated for basic compounds. These columns provide less retention, better peak shape, and higher efficiency for organic bases than can be obtained on conventional reversed-phase columns.

A high-performance liquid chromatographic method is described for determination of lidocaine (2-(dietyloamino)-N-(2,6-dimetylofenylo) acetamid) and its metabolite, monoethylglycine xylidide (MEGX), in human serum containing various concentration of bilirubin. Lidocaine and its metabolite were extracted from human serum using dichloromethane. After separation

A reversed-phase high-performance liquid chromatographic method with coulometric and UV detection has been developed for the simultaneous determination of morphine, morphine-3-glucuronide and morphine-6-glucuronide. The separation was carried out by using a Supelcosil LC-8 DB reversed-phase column and 0.1 M potassium

A HPLC-UV determination of clobazam and N-desmethylclobazam in human serum and urine is presented. After simple liquid-liquid extraction with dichloromethane the compounds and an internal standard diazepam were separated on a Supelcosil LC-8-DB column at ambient temperature under isocratic conditions

A simple HPLC method has been developed for the determination of ticlopidine in human plasma. Plasma samples were buffered at pH 9 and extracted with n-heptane-isoamyl alcohol (98.5:1.5, v/v). Imipramine was used as internal standard. Chromatography was performed isocratically with
M Molíková et al.
Journal of chromatography. A, 1217(8), 1305-1312 (2010-01-12)
The availability of ionic liquids (ILs) in wide areas of application often results in the requirement on their determination. The attention is also often focused on the knowledge of hydrophobicity as it plays a key role in the biological effects

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.

Can the Supelcosil LC-8DB HPLC column, Product 58354, be used for acidic compounds?
1 answer-
No, it is base treated, therefore acidic compounds will be adsorbed by the base treatment, resulting is peak tailing.
