Concept of response factor in capillary isotachophoresis. Determination of drugs in solution for intravenous injection.
Twenty-six drugs in solutions for intravenous injection were determined by capillary isotachophoresis with only one calibration point for each component. The maximum deviation of the labelled concentration was 2%. A new calibration constant is introduced, viz., the response factor (RF, dimensionless), which is independent of the diameter of the capillary, the construction of the universal detec...
متن کاملApplication 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 کاملIsotachophoresis superimposed on capillary zone electrophoresis
Applying isotachophoresis (ITE’) superimposed on capillary zone electrophoresis (CZE), which will be denoted the ITPlCZE mode, components migrate in an ITP way on top of a background electrolyte. In such an ITPKZE system the leading electrolyte consists of a mixture of an ionic species L, with a high mobility (the leading ion of the ITP system), an ionic species L, with low mobility (the co-ion...
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.
