Development of an analytical method for dibutyl phthalate determination using Surrogate analyte approach
Dibutyl phthalate (DBP) is a phthalic acid ester and is widely used in polymeric products to make them more flexible. DBP is found in almost every plastic material and is believed to be persistent in the environment. Various analytical methods have been used to measure DBP in different matrices. Considering the ubiquitous nature of DBP, the most important challenge in DBP analyses is the contam...
متن کاملSpecific creatinine determination in laboratory animals using the new enzymatic test kit "Creatinine-PAP".
The new Creatinine-PAP test kit from Boehringer Mannheim GmbH was evaluated for the determination of creatinine in dogs, rabbits, guinea pigs, rats, and mice. In comparison with methods based on the reaction with alkaline picrate, the enzymatic method gave the lowest serum creatinine values. The differences are caused by serum substances (non-creatinine chromogens) reacting with picric acid. No...

متن کاملResolving Spectra Overlapping Based on Net Analyte Signal for Simultaneous Spectrophotometric Determination of Fluoxetine and Sertraline
The net analyte signal standard addition method was used for simultaneous spectrophotometric determination of sertraline and fluoxetine in pharmaceutical preparations. The method combines the advantages of the standard addition method with the net analyte signal concept to enable the extraction of information about an analyte from the spectra of multi-component mixtures. This method uses full s...
متن کاملKinetic Analytical Method for Determination of Uric Acid in Human Urine using Analyte Pulse Perturbation Technique
Novos métodos simples e confiáveis para a determinação de ácido úrico (UA) são propostos e validados. Para a determinação quantitativa de UA, duas matrizes foram usadas: a reação oscilatória de Bray-Liebhafsky (BL) em um estado estacionário de não equilíbrio, estável, próximo ao ponto de bifurcação (método A), e o subsistema não oscilante (mistura de KIO3 e H2SO4), isto é, reação de Dushman (RD...
