6.7.2.5 Baseline Behavior
If wavelengths are switched during a data acquisition, the
chromatogram may show baseline jumps.
You can define how the baseline behaves in these cases:
• Zero : sets the baseline to zero
• Append : appends the baseline to the previous signal
• Free : lets the baseline "jump" to the current absolute value
TIP You can perform the AutoZero command (automatic null balancing)
any time during data acquisition, that is, the absorption measured at the
time of the autozero is subtracted from any absorptions measured
thereafter. Always select a time for
AutoZero at which no sample flows
through the cell.
