Extra info for Chemometric Methods in Capillary Electrophoresis
Different parameters or factors potentially can affect the results of a method. Several strategies can be applied to optimize (analytical) methods. When two or more factors need to be optimized, their influences on the response(s) can be examined by applying either univariate or multivariate approaches (7). A univariate method, such as the one-variable-at-a-time (OVAT) approach, varies only one factor at a time between consecutive experiments, while a multivariate procedure changes several factors simultaneously.
The different steps are discussed in more detail and illustrated with an example taken from the literature. 3. 1. Selection of Factors Before starting method development or robustness testing, the factors to be examined should be carefully defined and selected. Factors of CE methods can be divided into operational, environmental, and peak measurement/peak FACTORS AND THEIR LEVELS 19 analysis factors. Operational parameters are those that after optimization are described in the operating procedure of the method, while environmental factors are not necessarily specified in that procedure, for example, room temperature.
Selection of Levels In the screening phase of method development and in robustness tests, the factors usually are examined at two levels (−1, +1). On the other hand, in the response surface designs, applied in method optimization, the factors are examined at three or more levels, depending on the applied design (see further). In method optimization, the range between the levels is much larger than in robustness tests. Often, the range selected for a factor in optimization represents the broadest interval in which the factor can be varied with the technique considered.
