2 Concepts of 2D-LC
Multiple Heart-Cutting and High Resolution Sampling 2D-LC
This problem is addressed using a setup called multiple heart-cutting 2D-LC.
Here, the sampling loops on the 2D-LC valve are exchanged with
6-position/14-port selection valves, which are equipped with six loops each. In
this configuration, a peak can be cut out and stored, then analyzed as soon as the
second dimension is free.
