A factorial design to determine the effects of some variables in the long-term stability of methylmercury standard solutions in water

Abstract:

A factorial composite design has been employed for a rapid exploration of the effect of some parameters on the stability of spiked methylmercury iodide solutions. The analysis has been performed by capillary gas chromatography with electron-capture detection. The results obtained by the factorial and the univariate methods are in a good agreement. Although, the factorial design does not allow a discrimination of the significance among the same kind of factors, it greatly reduces the number of experiments when the different variables are investigated. © Springer-Verlag 1996.
