Maintenance

Periodic Checks
The frequency of maintenance required will be determined by the amount of use the
system receives, the cleanliness of the environment, and the number and nature of
the samples being analyzed. You should consider the usage of your spectrometer and
establish a suitable maintenance schedule, with particular emphasis on the following
areas of the system.
Torch Assembly and Plasma Induction Plates
Clean the torch components periodically according to the instructions given later in
this chapter to remove accumulated deposits. If using organic solvents, check the
injector and torch regularly for carbon buildup. Replace any cracked or worn O-rings
on the torch assembly.
The plasma induction plates must be kept clean to prevent arcing across the plasma
induction plates. Inspect the plasma induction plates for any deformations or carbon
buildup. Contact your PerkinElmer Service Representative to replace the plasma
induction plates if there are any signs of pitting. Pitting causes weakness in the
plasma induction plates which can result in a hole in the plasma induction plates and
a gas leak.
Purge Viewing Window/Tubes
Remove and examine the window or purge tube for deposits. If you notice a drop in
UV performance clean or replace the windows. Clean according to the instructions
given later in this chapter or replace as necessary.
Caution
Attention
To extend the life and aid in preventing devitrification of glassware, it is
necessary to remove all traces of alkali on glassware caused by handling it
with bare hands. To remove the alkali, wipe the glassware clean with
cotton wool dipped in alcohol.
Pour prolonger la durée de vie et de l'aide dans la prévention de la
dévitrification de la verrerie, il est nécessaire d'éliminer toute trace d'alcali
sur la verrerie provoquée par la manipulation à mains nues. Pour supprimer
l'alcali, essuyez la verrerie propre avec un coton imbibé d'alcool.
