Validação em métodos cromatográficos e eletroforéticos

Abstract: Recebido em 11/6/03; aceito em 2/12/03; publicado na web em 17/6/04 VALIDATION FOR CHROMATOGRAPHIC AND ELECTROPHORETIC METHODS. The validation of an analytical method is fundamental to implementing a quality control system in any analytical laboratory. As the separation techniques, GC, HPLC and CE, are often the principal tools used in such determinations, procedure validation is a necessity. The objective of this review is to describe the main aspects of validation in chromatographic and electrophoretic analy… Show more

“…The lowest level of recovery with the addition of the highest concentration of standard to the juices of both cultivars was observed only for D-glucose (Table 3). According to Ribani et al (2004), dispersion of results increases with the decrease in the concentration of the standard added to the samples. All the results found in the present study are within the acceptable limits established by Brazilian legislation for the validation of chromatographic methods (Agência Nacional de Vigilância Sanitária, 2003).…”

“…In recovery, the values found are in the range of 70 to 120% for all products screened [6]. For quantification of the PBZ samples of pulp was used external standard method [8,9,10], using standard curve obtained under the same conditions of the sample. The calibration curve was established correlating standard versus peak area, in concentrations 0.75, 1.0, 1.5, 2.0, 3.0 µg L -1 ( Figure 2).…”

“…Todos esses parâmetros são detalhadamente explicados nos diversos guias de validação e são constantemente revisados e discutidos. 98,108 Para o enfoque proposto nesta revisão, discutiremos os principais aspectos de validação analítica relacionados a métodos estabelecidos para a determinação de contaminantes químicos em alimentos, os quais envolvem o uso da MS como técnica analítica.…”
