7.2.7 Replacing the argon hose
The argon supply hose for the nebulizer may become discolored. In this case, the hose
must be replaced.
} Press the colored ring on the plug connector up and pull the hose down.
} Insert the new hose into the connection.
7.2.8 Changing the plasma compartment windows
The windows in the plasma compartment in front of the transfer optics must be re-
placed if their transmission has greatly deteriorated, especially in the UV range. Cleaning
the windows does not usually completely restore UV transmission. The cleaning effect
varies depending on the wavelength. Average losses of around 30% must be expected in
the UV vacuum. In the visible spectrum, transparency can generally be fully restored.
NOTICE
Risk of damaging the quartz windows due to sweat from hands and ultrasound
Fingerprints can burn into the surface of the quartz windows, reducing visibility.
¡ Do not touch the fronts of the quartz windows with your fingers. Wipe off any fin-
gerprints immediately with ethanol.
¡ Do not clean the quartz windows in an ultrasonic bath. This may lower the UV per-
meability of the windows.
