PARAMETERS AFFECTING SELECTIVITY IN PROGRAMMED ANALYSIS

The effects of changes in a parameter during a programmed elution will generally be the product of two independent factors  [Pg.257]

the relationship between the parameter that is being programmed and the retention [Pg.257]

An important characteristic of primary optimization parameters is that whereas they have a large effect on the capacity factors of the solutes, they have a relatively minor effect on the selectivity (a). This implies that the factors involved in optimizing an analysis program (the initial and final conditions, programming rate and shape of the program) do not affect the chromatographic selectivity to a large extent. This will be even more true [Pg.257]
