A new spectrofluorimetric method has been applied for determining salicylic acid in human serum for concentrations between 0.020 and \(0.252 \mathrm{ppm}\). The method was performed in an aqueous medium at \(\mathrm{pH}\) 6.0) attained by addition of phosphate buffer solution. The method is based on

A new method for the determination of triamterene for concentrations between 10 and 1000 ng ml-' by means of matrix isopotential synchronous fluorescence spectrometry and derivative techniques is proposed. This new method is useful for the determination of compounds in samples with unknown backgroun
A new fluorimetric technique is described for the determination of compounds in samples with unknown background fluorescence. The technique consists of performing synchronous scans through a trajectory which joins points of equal intensity of a fluorescent matrix tridimensional spectrum. The method
Simultaneous and direct assays of pyridoxal, pyridoxal-5'-phosphate, and pyridoxic acid in human serum are described. The method applied is based on the reaction of these compounds with beryllium in an ammoniacal medium to yield highly fluorescent derivatives. Overlapping of conventional fluorescenc
A simple, rapid, sensitive and selective method for the simultaneous determination of the non-stetoidal anti-inflammatory drug naptoxen (NAP) and its main metabolite the 6-demethylated derivative (DNAP) in human serum is described. The method is based on the intrinsic fluorescence of both acids in a
The determination of salicylamide and salsalate in human serum and urine is performed using a simple, rapid, sensitive, and selective method. The broad-band overlapping conventional spectra of both compounds are resolved by means of first derivative variable-angle synchronous fluorescence spectromet
