Example text

During the screening phase, screening designs are applied. These designs allow the examination of a relatively high number of factors in a rather small number of experiments. Usually the factors are evaluated at only two levels and two-level designs are applied. The results from screening designs are analyzed by estimating and interpreting the effects of the factors on the response(s) (4, 5, 7, 16) in order to determine those factors most influencing the outcome of the method. For the screening phase, the following steps can be distinguished: (1) selection of the factors to be evaluated and their levels; (2) selection of the screening design; (3) definition of the responses; (4) planning and execution of the entire experimental setup, and experimental determination of the responses; (5) calculation of the (factor) effects on the responses; (6) graphical and/or statistical interpretation of the estimated effects; and (7) identification of the factors most influencing the method performance.

2. Quantitative Factors. Quantitative factors are most often evaluated. They usually are described in the operating procedure and are used as such in the design, for example, capillary temperature. However, sometimes the selected factors by themselves do not represent a physicochemical property. These factors should preferably be defined in such a way that the effects can be linked to a physicochemical property. The following example illustrates this. A buffer can be defined either by the concentrations of its acid (Ca) and basic (Cb) compounds or by a given pH and ionic strength μ (5).
