Fraction transfer process in on‐line comprehensive two‐dimensional liquid‐phase separations

Two‐dimensional liquid‐phase separations have gained increasing attention for their ability to separate complex sample mixtures. Among the experimental setups used, an on‐line approach is preferred to reduce the probability of sample contamination, for easier automation and high‐sample throughput. The interfacing of the separation techniques in the on‐line mode brings additional demands on proper optimization of the two‐dimensional system. In...
