Multivariate optimisation of the experimental conditions for determination of three methylxanthines by reversed-phase high-performance liquid chromatography.
Nádia Machado de Aragão,Márcia Cristina da Cunha Veloso,Márcia Souza Bispo,Sergio Luis Costa Ferreira,Jailson B. de Andrade +4 more
TL;DR: The proposed RP-HPLC/UV method was suitable for quantification of these methylxanthines in coffee, tea and human urine samples and was validated in terms of limit of detection, limit of quantitation, linearity, recovery and the precision.
Journal ArticleDOI
Validação de métodos cromatográficos de análise: um experimento de fácil aplicação utilizando cromatografia líquida de alta eficiência (CLAE) e os princípios da "Química Verde" na determinação de metilxantinas em bebidas
TL;DR: In this paper, an HPLC experiment is proposed to verify the parameters of validation of chromatographic methods, based on green chemistry principles, which can be used in experimental courses of chemistry and related areas.
Journal ArticleDOI
Multivariate optimization of an ultrasound-assisted extraction procedure for Cu, Mn, Ni and Zn determination in ration to chickens
Joelia Martins Barros,Marcos A. Bezerra,Gisseli Souza Valasques,Baraquizio Braga do Nascimento Junior,Anderson Santos Souza,Nádia Machado de Aragão +5 more
TL;DR: Multivariate optimization techniques were used to develop a method based on the ultrasound-assisted extraction for copper, manganese, nickel and zinc determination from rations for chicken nutrition using flame atomic absorption spectrometry, and this method was applied in the analytes determination from chicken rations collected from specialized commerce in Jequié city.
