Variable Wavelength Detector (VWD)
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 test chromatogram has four main peaks with the following absorbances:
NOTE
The run time of the chromatogram is depending on the setting for response time (peak
width). If no stop time is set the chromatogram will repeat continuously.
