Priming the ISM

You must prime the ISM when it or the system that it is part of has never
been used. You must also prime it when you restart a system, after the system
has been idle for more then four hours, or when you change reservoirs or
solvents. During priming, the vent valve moves to the vent position, ensuring
minimal backpressure and directing the flow to waste. The flow rate during
priming is 4 mL/min.
Caution:
intermediate solvent, such as water, when changing from buffers to
high-organic-content solvents. Be sure to consult the solvent miscibility
tables in the Solvent Considerations section.
Ensure the solvent reservoirs contain sufficient solvent for adequate priming
and that the waste container can hold all the used solvent. For example, at
4 mL/min, priming for 5 minutes uses about 20 mL of solvent.
Warning:

in order for the degasser to function properly.
