Vanquish Loop Heart-Cut 2D-LC Systems

Confirm peak purity for more confidence in complex analysis.

Vanquish Loop Heart-Cut 2D-LC Systems

Increase your confidence in peak purity using the Thermo Scientific Vanquish Loop Heart-Cut 2D-LC System. This two-dimensional LC system (LC-LC) enables you to collect one or multiple fractions of the first-dimension separation in a sample loop and transfer the cut-out fraction(s) in an automated workflow to a second-dimension separation. Heart-Cut 2D-LC can reveal hidden impurities that co-elute with the analytes of interest by using two complementary column chemistries to gain more separation power. The system is configured using modules from the Vanquish Core HPLC, Vanquish Flex UHPLC or Horizon UHPLC systems, retaining all the performance, robustness and ease of use of the Vanquish LC platform.


Highlights

Greater confidence

Collect one or multiple fractions of the first-dimension separation in a sample loop and transfer the cut-out fraction(s) to a second-dimension column with complementary column chemistry in an automated workflow for more confidence in peak purity.

Flexibility 

The modularity of Vanquish LC systems makes it easy to build a system to best suit your application requirements and upgrade a standard HPLC instrument to more advanced 2D-LC configurations when you need to address more challenging analyses.

Save time and resources

The integrated LC-LC system in combination with automated workflows, with predefined fractionation and transfer steps, allow for unattended sample analysis while reducing human error and saving time and bench space compared to offline approaches.

Easy and reliable tool-free connections

The Vanquish Loop Heart-Cut 2D-LC system is fitted with Thermo Scientific Viper fingertight fittings, which support near-zero dead volume connections and enable sharper peaks and tool-free setup

CDS software

The Vanquish 2D-LC systems seamlessly integrate with our Thermo Scientific Chromeleon Chromatography Data System (CDS) to deliver superior compliance tools, networking capabilities, automation and data processing. 


What is loop-based heart-cut 2D-LC?

Our loop-based heart-cut 2D-LC system allows you to automate and cut-out fractions(s) of the eluent of the first-dimension (¹D) column into a sample loop to undergo a second separation on a complementary second-dimension (²D) column to resolve difficult or co-eluting peaks.

 

This flow scheme illustrates a Vanquish Online 2D-LC system for multiple heart-cutting by storing the cut-out fractions in multiple loops before performing a complementary analysis on a second-dimension (²D) column.
