there is a large change. A ramp is a linear change from the current flow rate
to the new flow rate, over the set duration. The Agilent SD-1 can handle
large abrupt changes in flow rate without any problem, but the HPLC
column may be damaged by pressure shock resulting from such abrupt
changes.
blocked, for instance by the operation of the sample inject valve, a pressure
spike well in excess of the set pressure limit may be generated. This spike
may even exceed the capacity of the outlet tubing and/or fittings.
