Essential Theory of HPLC - Chromatography Online
2019年1月1日 · In this way, we can predict the optimum gradient time based on the other parameters within the method. In order to generate an “ideal” k* value of five, in this case a gradient value of 12.75 min would have produced a more ideal separation than the original time of seven minutes. We may also use another very useful relationship that defines an adjusted gradient steepness (G s), and which ...
