Application of Capillary Isotachophoresis in Phenothiazines Determination
The phenothiazine derivatives such as: promethazine, chlorpromazine and thioridazine hydrochlorides are used as psychotropic, neuroleptic, local anesthetics, anti-allergic and antiyomiting drugs [1]. The therapeutic interest in these compounds group justifies research to establish different analytical methods for the determination of these drugs in pharmaceutical preparations and biological sam...
متن کاملDetermination of 4-methylimidazole in caramel color by capillary isotachophoresis.
A method for the determination or 4-methylimidazole in caramel color, based on cationic separation of the sample by capillary isotachophoresis, is described. No pretreatment of the sample is necessary and the detection limit was found to be 5 ppm.
متن کاملDetermination of glycyrrhizin in liqueurs by on-line coupled capillary isotachophoresis with capillary zone electrophoresis.
An on-line coupled capillary isotachophoresis-capillary zone electrophoresis method for the determination of glycyrrhizin in liqueurs is described. The optimised electrolyte system was 5 mM HCl+11 mM epsilon-aminocaproic acid+0.05% hydroxyethylcellulose+30% methanol (leading electrolyte), 5 mM caproic acid+30% methanol (terminating electrolyte) and 20 mM caproic acid+10 mM histidine+0.1% hydrox...
متن کاملSimultaneous determination of iodide and iodate in seawater by transient isotachophoresis-capillary zone electrophoresis with artificial seawater as the background electrolyte.
We developed capillary zone electrophoresis with transient isotachophoresis (ITP) as an on-line concentration procedure for simultaneous determination of iodide and iodate in seawater. The effective mobility of iodide was decreased by addition of 20 mM cetyltrimethylammonium chloride to an artificial seawater background electrolyte so that transient ITP functioned for both iodide and iodate. Li...
متن کاملSimultaneous determination of chloride, sulphate, orthophosphate and organic anions in human urine by capillary isotachophoresis.
The principle of isotachophoresis has been used to develop a simple, specific and sensitive analytical method for the determination of anions in untreated urine. Isotachophoretic separation of anions in the presence of complex-forming counter ions (e.g. Cd2+) enables the quantitative separation and determination of chloride, sulphate and orthophosphate in the same sample and the less accurate m...
