the plasma is extinguished.
To save on argon costs, you can turn the polychromator boost off
overnight, by deselecting Polychromator > Boost on the Status
tab on Instrument window. 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
pressure bar (refer to Figure 11).
b
Allow the pressure bar to swing downwards.
c
Lift the tubing out of the grooves.
