In the present work, capillary electrophoresis with contactless capacitive coupled conductivity detection (CE-C4D) was used for the development of two rapid methods for simultaneous determination of: (i) diphenhydramine (DIP) and ammonium; (ii) arginine (ARG), ascorbic acid (ASC) and aspartate (ASP). The proposed methods are characterized by analyzes with run times less than 50 s and can be used in quality control of raw materials and pharmaceutical formulations having such compounds in its composition. In the simultaneous determination of the compounds of the group (i), the BGE was composed by 30 mmol L-1 of 2 (N-morpholino) ethanesulfonic acid (MES) and 15 mmol L-1 LiOH (pH=6,0). The limits of detection (LOD) were 0.04 and ...
