Spectrophotometric determination of zinc in copper-base alloys with TAN
(1995)
TAN reacts with zinc(II) forming a red complex with composition 1:2 Zn(II)-TAN and absorption maximum at 582 nm. Zinc can be determined with this reagent in the presence of Triton X-100, in the pH range 6.20-8.00 with a ...
Validation of UV spectrophotometric method for determination of lomefloxacin in pharmaceutical dosage form
(2005-07-01)
A simple and reproducible method was developed for the assay of lomefloxacin in tablets. The excipients in the commercial tablet preparation did not interfere with the assay. Beer's law is obeyed in the range 2.0-9.0 μg.mL-1 ...
Development and validation of an UV spectrophotometric method for determination of gatifloxacin in tablets
(2005-04-01)
A simple, sensitive and accurate spectrophotometric method was developed for the assay of gatifloxacin in raw material and tablets. Validation of the method yielded good results concerning range, linearity, precision and ...

Simultaneous determination of chlordiazepoxide and clidinium bromide in pharmaceutical formulations by derivative spectrophotometry
(1999)
A direct and simple first derivative spectrophotometric method has been developed for the simultaneous determination of clidinium bromide and chlordiazepoxide in pharmaceutical formulations. Acetonitrile was used as solvent ...
Diagnosis of Smith-Lemli-Opitz syndrome by ultraviolet spectrophotometry
(Associação Brasileira de Divulgação Científica (ABRADIC), 2003-10-01)
Smith-Lemli-Opitz syndrome (SLOS) is an autosomal recessive disorder due to an inborn error of cholesterol metabolism, characterized by congenital malformations, dysmorphism of multiple organs, mental retardation and delayed ...
