If you would like immediate operation next time the MP-AES
instrument is started, leave the PC and gas on. Close the worksheet

Extinguish the plasma by choosing Plasma Off from the Plasma
button drop-down arrow or pressing SHIFT and F5 on the
keyboard. The peristaltic pump stops automatically when the
plasma is extinguished.
The mains power switch can be left on.
To increase the pump tubing lifetime, loosen the pressure on the
peristaltic pump tubing by releasing the pressure bars and lifting
the tubing out of the grooves in the tube retainer. To do this:
a
Push up the pressure bar tensioners. (1 in Figure 5). This
releases them from the pressure bar.
b
Allow the pressure bar to swing backwards. (2 in Figure 5)
c
Lift the tubing out of the grooves in the tube retainer. (3 in
Figure 5)
