Application of capillary zone electrophoresis to the quantitative estimation of cimetidine in rat urine is described. A series of steps, which include extraction with ethyl acetate and petroleum ether, are used to remove compounds which caused poor capillary performance. The method is based on the r

## Abstract This paper describes a method for analysing some acids of milk whey by Capillary Zone Electrophoresis. After eliminating the whey proteins by ultrafiltration, the whey underwent electrophoretic separation in the presence of anodic electroosmotic flow. The following analytes were detecte
## Abstract A CZE with indirect LIF detection method was used for the determination of uric acid (UA) in human urine. UA and its coexisting analytes (__i.e__. hypoxanthine, xanthine and ascorbic acid) could be well separated within 4.5βmin at a voltage of 25βkV with 25Β°C cartridge temperature in a
This study shows an improved method for the determination of L-ascorbic acid (L-AA) in fruits of Lycopersicon by capillary zone electrophoresis (CZE). Two backgrounds electrolytes (BGEs) have been tested: (i) 400 mM borate at pH 8.0 and 1 Ψ 10 Ψ2 % hexadimethrine bromide, for the separation of Eulyc
