Direct fluorometric determination of urea in urine.
Urea in biological fluids has been determined by a variety of direct and indirect procedures. Some indirect methods depend on the hydrolysis of urea with the enzyme urease to form ammonia, with subsequent quantitation of the ammonia by nesslerization (1-4). Undesirable features of these indirect methods are the use of relatively unstable reagents and loss of ammonia during the procedure. Direct...
متن کاملAutomated fluorometric determination of amphetamine in urine.
A completely automated fluorometric determination of amphetamine in urine is described and evaluated. The dihydrolutidine derivative produced by reaction of amphetamine with formaldehyde and acetylacetone is excited at 410 nm and the resulting intensity of fluorescence measured at 476 nm. The working limit of detection of amphetamine in fresh urine (1.5-mi samples) is 0.15 mg/liter. A result is...
متن کاملRapid fluorometric estriol determination in pregnancy urine.
curves of precipitation are shown in Figure 1. Ampicillin, carbenicillin, amoxycillin, procaine penicillin, cephalothin, salicylic acid, acetylsalicylic acid, and dexamethasone caused no interference. The presence of methicillin in urine may be differentiated from the turbidity attributable to protein by measuring the absorbance at different intervals during the reaction, such as 0.5 and 5.0 mm...
متن کاملCorrelation between fluorimetric and microbiological methods for determination of cephalexin in urine and serum.
The fluorimetric and microbiological methods for the determination of serum and urine cephalexin were compared with the aid of coded samples in two different laboratories. The coefficient of correlation between the two methods for serum cephalexin was 0.94. At urine cephalexin concentrations above 0.5 g/l, the coefficient of correlations between two methods was 0.83. At lower concentrations (0....
متن کاملHigh speed liquid chromatographic determination of cephalexin in human plasma and urine.
A rapid and accurate high speed liquid chromatographic method has been developed for the determination of cephalexin in human plasma and urine. The method involves micropore filtration of urine specimens and methanol extraction of plasma samples followed by HSLC separation on a bonded reverse phase column utilizing a mobile phase of methanol-water containing acetic acid. The quantitativity of U...
