CAUTION Do not use cleaning wire or abrasives like brushes or a scourer to clean the torch.
Hot Surface and Chemical Hazard
WARNING
The torch and torch compartment become extremely hot during instrument
operation and remain hot for some time after the instrument has been
switched off. Allow the torch and torch compartment to cool for at least five
minutes before attempting to remove the torch. Use heat-resistant gloves.
Nitric acid, hydrochloric acid and strong alkali solutions are very corrosive
and can cause severe burns when they come into contact with the skin.
Preparation of acid soak solutions and any soaking should be done under an
extraction fume hood. It is essential that appropriate protective clothing be
worn at all times when handling these acids. If acid contacts the skin, wash
off with copious amounts of water and seek medical attention immediately.

Important

Use a clean, wide diameter, open-top beaker (preferably 100 mL tall form) or a
similar container to hold the soak solutions. Use the recommended torch cleaning
stand (see Figure 15A) for 5800/5900 ICP-OES Easy-fit torches (part number
G8010-68021) to hold the torch inverted while soaking during the cleaning
process. The torch cleaning stand aids in cleaning the torch, preventing damage to
the fragile end of the quartz outer tube and limiting exposure of the elastomer
materials on the torch body to acid fumes, reducing premature degradation.

Agilent 5800 and 5900 ICP-OES User's Guide
Use clean/particle free detergents or acid to perform the soak.
Ensure the acid does not contact the seal between the quartz outer tube and
the plastic base.
Do not soak the removable top seal of semi-demountable torch.
Keep the torch vertical, with the ball joint at the top, throughout all cleaning
and rinsing steps unless otherwise directed.
Do not remove the torch adhesive cap on the one-piece torch that covers the
seal between the quartz and the plastic.
For a better clean, always disassemble the semi- or fully demountable torch
during rinsing and drying procedures.
