Este trabalho descreveu e comparou quatro estudos entre si que utilizaram métodos automáticos em fluxo com detecção espectrofotométrica e a reação de oxidação do diclofenaco para determinar diclofenaco em formulações farmacêuticas e fluidos corporais. Para isso, utilizamos os seguintes artigos: Versatility of a multicommuted flow system in the spectrometric determination of three analytes, Sequential injection spectrophotometric method for the assay of anti-inflammatory diclofenac sodium in pharmaceutical preparations, Screening of conditions controlling spectrophotometric sequential injection analysis e Sequential injection spectrophotometric determination of diclofenac in urine and pharmaceutical formulations e detalhamos as metodologias empregadas, os resultados, conclusões obtidas e comparamos entre eles os limites de detecção, desvio padrão relativo e a frequência analítica. Os resultados mostraram diferenças significativas entre métodos empregados e a utilização do Sistema automático do tipo Análise por Injeção Sequencial, apesar deste possuir menor frequência analítica.

Job's Method

Simple, rapid and sensitive extractive spectrophotometric method is presented for the determination of glibenclamide (Glb) based on the formation of ion-pair complex between the Glb and anionic dye, methyl orange (MO) at pH 4. The yellow colored complex formed was quantitatively extracted into dichloromethane and measured at 426 nm. The colored product obeyed Beer’s law in the concentration range of (0.5-40) μg.ml-1. The value of molar absorptivity obtained from Beer’s data was found to be 31122 L.mol-1.cm-1, Sandell’s sensitivity value was calculated to be 0.0159 μg.cm-2, while the limits of detection (LOD) and quantification (LOQ) were found to be 0.1086 and 0.3292 μg.ml-1, respectively. The stoichiometry of the complex created between the Glb and MO was 1:1 as determined via Job’s method of continuous variation and mole ratio method. The method was successfully applied for the analysis of pharmaceutical formulation.

Recent study was conducted to develop a simple UV spectrophotometric method to determine Phenytoin in bulk and injection form according to official requirement and validate as per ICH guidelines. λmax of Phenytoin was found 202 nm. Linearity existed perceived in the concentration assortment 2-8 μg/ml (r2 = 0.999) for the method. The method was validated pertaining to linearity, precision and accuracy studies, LOD and LOQ consistent with ICH guidelines. The existent method was establish to be simple, linear, precise, accurate as well as sensitive and can be applied for routine quality control enquiry for the analysis of Phenytoin in bulk and injection form.
