LC Control Manual Flow

The LC Control Manual Flow dialog accessible through using the Modify Gradient… button from Device Monitor window allows the user to set a custom mobile phase composition and flow while the analysis is running. It resembles the Method Setup - LC Gradient tab in functionality.

LC Control Manual Flow dialog

The LC Control Manual Flow dialog is only available while an analysis is running. When it is invoked and the OK button is pressed, the original Gradient Table from the acquisition method is discarded and replaced by the Gradient Table from the LC Control Manual Flow dialog. Any such operation is recorded in the audit trail of the measured chromatogram.

Caution:

After the analysis run which used manual flow changes ends, the original method is automatically sent to all controlled devices to make sure Clarity station returns to the original method.
