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

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.
