Test Chromatogram - Agilent Technologies 1220 Infinity II LC User Manual

Test Chromatogram

A built-in pre-defined test chromatogram on the VWM board is processed
through ADC like normal signals from the diodes and can be used to check the
ADC and the data handling system. The signal is available at the analog output
and on the GPIB.
The run time of the chromatogram is depending on the setting for response time (peak
N O T E
width). If no stop time is set the chromatogram will repeat continuously.
