Integrator Delay
The integrator delay is used to delay the start of integration after the analysis begins.
It is used to prevent integration of peaks which may appear as a result of pressure
changes during sample injection, especially when large syringe injections are made.
If you have more than 25 peaks in an analysis, integrator delay may be used to
determine which 25 peaks will be identified. If you are interested in the peaks in the
middle or at the end of the chromatogram, set the integrator delay so that the first
peaks are not integrated.
1. Press Enter Menu, SETUP, CONFIG, COLUMN.
2. Select the column for which you want to alter the integration settings. Disable
