Quick-Change Adjustable Torch Module
Cleaning the Torch
The torch components should be cleaned regularly to remove accumulated
deposits. After prolonged use, a torch may lose its transparency and become
crystalline. In this condition, called devitrification, the torch is very fragile. You
should not attempt to clean a devitrified torch, but it can still be used. If the torch
is cloudy, this generally does not affect performance because the plasma is either
viewed through the slot on the torch, or, for axial viewing, through the open end of
the torch.
If you have been analyzing aqueous solutions, the torch glassware and injector tube
should be cleaned in an acid bath. An ultrasonic bath may be used. Start with a
solution of 5% nitric acid or aqua regia and, if deposits persist, increase the acid
concentration, up to 20% if necessary. Acid solutions must be used with care.
Observe all of the manufacturer's safety recommendations. These
recommendations are normally provided in a material safety data sheet (MSDS)
supplied with the chemical.
Use of hydrofluoric acid for cleaning the torch is
not
recommended.
If you have been analyzing organic solutions, the torch glassware and injector tube
can be cleaned using a solvent or diluted soap solution. Be sure to inspect the torch
and injector daily for carbon buildup. A muffle furnace can be used if necessary to
remove organic deposits on the torch or injector. Place the torch or injector in a
muffle furnace at 500
C to 550
C for several hours.
After cleaning the torch, dry it thoroughly using clean air or nitrogen. No moisture
should be present.
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.
