## Abstract The ionization constants of nine basic drugs (ethylmorphine, thebaine, codeine, levorphanol, dihydrocodeine, cocaine, alprenolol, propranolol and methamphetamine) in methanol were determined from the dependence of their mobilities on the pH\* of the background electrolyte (BGE), based o

## Abstract Large‐volume sample stacking (LVSS) is an effective on‐capillary sample concentration method in capillary zone electrophoresis, which can be applied to the sample in a low‐conductivity matrix. NaOH solution is commonly used to back‐extract acidic compounds from organic solvent in sample
