Valve Configurations
Agilent InfinityLab 2D-LC Solutions offer two general valve configurations that
decide which of the 2D-LC modes that can be used with the instrument. While the
Single Heart-Cutting (SHC) configuration offers access to Single Heart-Cutting
and Comprehensive 2D-LC, the Multiple Heart-Cutting (MHC) configurations
additionally gives access to Multiple Heart-Cutting and High-Resolution Sampling
2D-LC. In addition, the Active Solvent Modulation valve (G4243A) is only available
for the MHC configuration. An overview of all available 2D-LC modes can be
found in Optional hardware configurations
Stack setups of all other LC modules (reference) remain valid since those setups
are independent of the valve configuration.
