Preparations
•
Finish any pending acquisition job.
•
Stop the flow at the pump and remove the solvent lines from the eluent bottles to avoid spilling
solvent.
•
Close the shutoff valves at the pump if available.
NOTE
If the sampler with 900 µL metering device is linked to a 1260 pump, such as the
G7112B Binary Pump, the 400 bar pressure limit must be set manually in the
method parameter settings of the pump (see
Setup of Basic Pump Parameters
chapter in the pump user manual). For all 1290 pumps, the pressure limit will be
set automatically.
NOTE
When the instrument setup has changed, configure the new setup in the online
view of the Chromatographic Data System. See
