Determination of free catecholamines in urine by tandem affinity/ion-pair chromatography and flow injection analysis.
BACKGROUND A system was developed for the simultaneous measurement in urine of free catecholamines (i.e., dopamine, norepinephrine, epinephrine) and creatinine (i.e., an indicator of urine output and volume). This method was based on the use of tandem affinity/ion-pair HPLC and flow injection analysis. METHODS The free catecholamines were extracted directly from urine by using an on-line phen...
متن کاملExtraction and Determination of Cyproheptadine in Human Urine by DLLME-HPLC Method
Novel dispersive liquid-liquid microextraction (DLLME), coupled with high performance liquid chromatography with photodiode array detection (HPLC-DAD) has been applied for the extraction and determination of cyproheptadine (CPH), an antihistamine, in human urine samples. In this method, 0.6 mL of acetonitrile (disperser solvent) containing 30 µL of carbon tetrachloride (extraction solvent) was ...

متن کاملThiocyanate determination by ion pair chromatography
Department of Analytical and Environmental Chemistry, Vilnius University, Naugarduko 24, LT-03225 Vilnius, Lithuania A simple and rapid ion pair chromatographic method has been developed for the determination of thiocyanate. Separation was carried out on a 25 cm × 4.6 mm Ascentis C18 column (5 μm particle size) with a mobile phase containing 2 mmol/l tetrabutylammonium (TBA)-phosphate (pH 6.5) ...
متن کاملRapid Determination of Lead in Urine by Ion Exchange.
For routine screening of employees in the lead industry, a method for determination of urinary lead was developed in which this element is removed from urine by means of a chelating agent, eluted, and determined by a modified dithizone method. The method gives values which are about 5% below those obtained by the wet ashing technic, with a precision of ± 2.1% in the range of 2-15 jig. of lead p...
