What is online 2D-LC?

Two-dimensional liquid chromatography is a multidimensional separation technique to achieve full characterization of substances or peak purity confirmation. One compound, or one fraction, is analyzed by two different separation modes to add additional selectivity to resolve difficult analytes or deplete interfering matrix.

There are different types of 2D-LC techniques differing in automation degree, as well as number and storage of fractions. Unlike offline 2D-LC where fractions are collected and then re-injected onto a second column, online 2D-LC involves transferring the fractions of the first-dimension separation to a second-dimension column in a single flow path inside the system.

Straightforward peak purity confirmation by LC-LC

The Thermo Scientific Vanquish Loop Heart-Cut 2D-LC System can reveal hidden impurities that co-elute with the analytes of interest by using two complementary column chemistries to gain more separation power. This system enables you to collect one or multiple fractions of the first-dimension separation in one or multiple loops and transfer the cut-out fraction(s) in an automated workflow to a second-dimension separation.

Enhance freedom and performance of 2D-LC method combinations

The Thermo Scientific Vanquish Trap Heart-Cut 2D-LC System facilitates a wide range of 1D and 2D separation combinations and simplifies multi-dimensional LC method development. It can reveal hidden impurities that co-elute with the analytes of interest by applying two complementary column chemistries to gain more separation power. This system enables you to collect a single fraction of the first-dimension separation onto a trap column to pre-concentrate low-abundant analytes and addresses solvent incompatibility issues before the fraction is eluted onto a second dimension (2D) column to resolve difficult or co-eluting peaks.
