This makes it necessary to have a strict quality control for compliance with local regulationsObjective:To verify and compare AOAC standard methods 969.09 by UV-Vis spectrometry and the respective CIPAC method by HPLC. Method:The guidelines described by the Costa Rican Accreditation Body (ECA) were followed to verify analytical performance parameters in standardized methods. Results:The UV and HPLC methods proved suitable but hadsignificant differences in the results.Conclusions:Both methodologies comply with the requirements but we recommend an enlarged test with moreanalysts and laboratories to define which is more accurate. 2020 artículo científico 1659-4266 https://www.redalyc.org/articulo.oa?id=515664454022 es http://www.redalyc.org/revista.oa?id=5156 UNED Research Journal / Cuadernos de Investigación UNED application/pdf Universidad Estatal a Distancia UNED Research Journal / Cuadernos de Investigación UNED (Costa Rica) Num.2 Vol.12 |
