Preparation conditions for samples of biological fluids (urine, blood) for electrophoretic identification of basic nitrogen-containing compounds with the aid of a Kapel-105 capillary electrophoresis system have been studied. It is demonstrated that bupivacaine, lidocaine, and azaleptine can be identified in biological fluids in the presence of coextracted substances using electrophoretic spectra and quantitative indices (pKa).
