3. LC×LC method development

Whether offline or online, it is necessary to find a sufficiently orthogonal LC×LC combination. In offline LC×LC, the two dimensions can then be optimized independently of each other, the method development being that conventionally used in LC. In online LC×LC, development is more complicated, as the two dimensions are linked and must therefore be optimized simultaneously.

3.1 Searching for orthogonality between the two dimensions

The first step in LC×LC method development is to select two chromatographic systems (figure 4...
