High-performance liquid chromatography (HPLC), over-pressured-layer chromatography (OPLC) and thin-layer chromatography (TLC) techniques with micellar mobile phases were proposed to evaluate the lipophilicity of 21 newly synthesized 1,2,4-triazoles, compounds of potential importance in medicine or agriculture as fungicides. Micellar parameters log k(m) were compared with extrapolated R(M0) valu...

Article history: Received on: 30/07/2013 Revised on: 25/12/2013 Accepted on: 09/01/2014 Available online: 30/01/2014 Micellar liquid chromatography (MLC) is one of the very important analytical techniques. It contains mobile phase added with surfactants above its critical micellar concentration and the stationary phase is modified with surfactant monomers. So, micelles alter the solubilising ca...

Amoxicillin, a β-lactamase inhibitor, is one of the most commonly prescribed drugs in the treatment of urine and skin structure infections. In this work, amoxicillin was...

the use of aqueous mixed micellar system consisting of sodium dodecyl sulfate (sds) and polyoxyethylene (23) dodecanol (brij-35) as the mobile phase in reversed-phase liquid chromatography was studied. a group of chlorophenols was used as the test mixture. adding organic modifier to the system showed that the use of low concentrations of organic additives improves efficiency in sds/brij-35 mixe...

a multiple linear regression model is proposed to calculate capacity factor of  analytes using structural features computed using hyperchem software. the  chemical descriptors of analytes were computed using hyperchem software and  regressed against the experimental capacity factors of analytes collected from the  literature. the absolute average percentage deviation (aard) and individual perce...
