Each subsequent tick mark occurs at 10-drop intervals. The drophead advances at
10-drop intervals following the start of the run. Note that if the delay size equals the
fraction size, the start/run mark and the first event mark are superimposed. This
means that the first observed tick mark (following the start/run mark) corresponds to
the second fraction advance.

Example: Peak Collection by Threshold and Delay
shows an example in which Delay is used during the collection of peaks
by threshold. Assume the following for the run:
Flow rate
1 ml/min
Peak fraction size
1 min
Delay time
0.25 min
Threshold value
10% AUFS
Non-peak destination
Waste
