Etching the Cyclonic Spray Chamber
The cyclonic spray chamber can be etched in order to improve drainage using the
following procedure. However, if you will be using the cyclonic spray chamber in
determinations of silicon, this procedure should
not
be used.
1. Prepare a 0.5% solution of hydrofluoric acid (HF), observing the precautions
listed above.
2. Ignite the plasma.
3. Aspirate the HF solution for between 1 and a maximum of 2 minutes.
4. At first, you will see beads of water inside the cyclonic spray chamber, then after
approximately 30 seconds, the beads will begin to disappear.
5. Aspirate a rinse solution for several minutes.
Hydrofluoric acid — toxic and corrosive.
Hydrofluoric acid (HF) is toxic,
extremely
corrosive, and can cause
severe burns.
Hydrofluoric acid will readily burn skin, and if the
fumes are inhaled, lung tissue. Burns may not be immediately painful
or visible. Contact with eyes could result in blindness.
•
When using hydrofluoric acid, always wear suitable protective
clothing including a face mask, work in a fume hood, and observe the
manufacturer’s instructions and your local safety regulations.
Avertissement: L'acide fluorhydrique - toxique et corrosif.
L'acide fluorhydrique (HF) est toxique, extrêmement corrosif et peut
causer des brûlures graves.
L'acide fluorhydrique sera facilement
brûler la peau, et si les vapeurs sont inhalées, les tissus pulmonaires.
Les brûlures peuvent ne pas être immédiatement douloureuses ou
visibles. Contact avec les yeux peut entraîner la cécité
.
•
Lors de l'utilisation de l'acide fluorhydrique, toujours porter des
vêtements de protection appropriés, y compris un masque, le travail
dans une hotte, et observer les instructions du fabricant et vos règles
de sécurité locales.
