Screen
A common screen layout is used for the concentration analysis history screen, retention time
history screen, and calibration factor history screen.
These screens display the changes over time of concentration analysis data, retention time data,
and calibration factor data, respectively, as measured by the active GCM.
Each screen can contain up to 999 peaks. The maximum displayable number of analysis clock
times is limited to 250 for concentration analysis history and retention time history, and to 100 for
calibration factor history.
Screen components are as shown below.
