Implementing 2D-Liquid Chromatography on Aconitum pendulum Samples for Enhanced Compound Separation

To begin the 2D liquid chromatography, or 2DLC, double-click the instrument one online icon, and the chemical workstation will automatically communicate with the 1260LC and enter the workstation. For the 2DLC method parameter setting, click on the Injector module, right-click Method and set the injection volume, flow rate, and mobile phase time gradient of the 1D pump. Enter the sample runtime under Stop Time.

Click on the main menu instrument and click 2DLC Method on the dropdown menu. Select Comprehensive in 2DLC mode. Enter two minutes at modulation time and 1.9 minutes at 2D gradient stop time.

Set flow settings to two milliliters. Edit 2D gradient and set wavelengths. After editing the method, select Save Method As on the method menu to name the new method, and click OK.
