Periodic Checks; Torch Assembly And Plasma Induction Plates - PerkinElmer AVIO 500 Customer Hardware And Service Manual

Be sure the drain tubing is firmly attached to the spray chamber and liquid flows
smoothly through the pump. Keep the drain tubing clear of debris. Empty the drain
bottle as needed.

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.
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.

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.
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.
