Paused state, the pump, peak detection, and fraction
collection will not operate. While stopped, you can save
the run data by clicking the Save button, abort the run
by clicking the Rewind or Fast Forward buttons, or

If you have stopped the run before its programmed run
length has elapsed, the current method is modified using

the next run, or can be saved for future runs.
• Fast Forward — Click this button to jump to the next
step of a run. Once you've started a run, the system
performs several steps. The first step is to deliver
solvents using the programmed gradient for the entire
run length. When this step is complete, the system will
purge the column with air. Following this, the system
will clean the injection valve.
Clicking the Fast Forward button will cause the system
to skip any remaining time in the current step and
advance to the beginning of the next step. Unlike the
Rewind button, the Fast Forward button will not modify
the current method's run length setting.
