To save on argon costs, you can turn the polychromator boost off
overnight, by choosing PolyBoost off from the Analyze menu.
This is not recommended if you are routinely analyzing lines
below 190 nm, as the instrument will take some time to stabilize
when the polychromator boost is turned on again.
To increase the pump tubing lifetime, loosen the peristaltic pump
tubes by releasing the pressure bars and lift the tubes out of the
grooves. To do this:
a
Push up the pressure bar screws. This releases them from the
resting bar (refer to Figure 8).
b
Allow the resting bar to swing downwards.
c
Lift the tubing out of the grooves.
Figure 7. Peristaltic pump with pressure bars pushed up and resting bar
freely down, allowing tubing to be loosened
It is recommended that you switch off the water cooler.
