Fluorimetric determination of cefuroxime in body fluids.

Fluorimetric determination of isoxsuprine hydrochloride in pharmaceuticals and biological fluids.

Two simple and highly sensitive fluorimetric methods have been developed for the determination of isoxsuprine hydrochloride in bulk, in dosage forms and in biological fluids. The first method involves the direct measurement of the native fluorescence of the drug in the concentration range 0.4-4.0 microg ml(-1), the second method is based on the oxidation of isoxsuprine HCl with cerium(IV) follo...

Bromide determination in body fluids.

Fluorimetric determination of creatine.

STRONGLY ALKALINE SOLUTIONS ninhydrin (1,2,3 indantrione hy) combines with guanidine, monosubstituted guanidines, and disubstituted guanidines to form highly fluorescent addition ucts (1). This reaction has been used as the basis for a simple, itive fluorimetric method for the determination of creatine in m, blood, and urine. he most widely used methods for determining creatine are based n the ...

Electrochemical Determination of Amitriptyline using a Nanocomposite Carbon Paste Electrode in Human Body Fluids

A carbon nanocomposite electrode has been designed by incorporation of montmorillonite nanoclayinto the carbon ionic liquid electrode for the electrochemical determination of amitriptiline . The surface ofthe proposed electrode was characterized by scanning electron microscopy. The presence of ionic liquid asa binder is believed to be responsible for the electrocatalytic activity of the propose...

Improvements in the fluorimetric determination

The RNA/DNA ratio is a useful indicator of the nutritional condition of fish larvae. The presented analytical procedure is an improvement of Clemmesen's (Meeresforschung 32: 134-143, 1988) methodology which involves purification of fish larvae tissue homogenates and subsequent fluorescence-photometric measurements using specific nucleic acid dyes. The modifications concern the homogenization an...
