“…This is especially true for larger sample injection widths, as they will require longer focusing times that may not be feasible for a given chamber length. On another note, it would also be helpful to consider situations where the sample injection is focused in the height direction [
40], as this could limit peak tailing at large
values. Interestingly, the mixing parameter
can provide a useful reference for the level of focusing that is required in the height direction to mitigate the peak tail.…”
