Description

A new approach is developed through a combination of matrix representation and higher derivative spectrophotometry and can be used to analyse seven four-component mixtures of lanthanide ions, simultaneously, with a recovery of between 92.0 and 107.1%. The method is rapid, sensitive and accurate and is suitable for a large number of samples. (Author)
