8. Maintenance
NOTE
Extinguish the plasma at least once a day to perform, for example, maintenance of
the glassware and to check that there is no condensation on the parts.
8.1 Replacing and Inspecting Glassware
The glassware inside the ICP stand must sometimes be cleaned or replaced. The approximate
replacement period and the replacement procedure are given below.
WARNING
Risk of Burn Injury
There is a risk of burn injury. Do NOT touch the plasma stand interior for 3 minutes
after the plasma is extinguished.
The glassware is fragile. Handle it with care.
8.1.1 Replacing the Torch
Replace the torch in the following cases.
* If the torch melts (periphery)
* If samples adhere to the torch's center orifice
* If, after analyzing high-concentration boron (B), a trace amount of another element is to be analyzed
* If the torch's center orifice melts or is damaged in some other way
NOTE
Even if the internal diameter of the tip of the torch's center orifice becomes smaller,
this cannot be checked with the torch installed. If the spectra for an element do NOT
appear or if the intensity weakens, it is possible that the tip of the torch's center
orifice has melted or the internal diameter has changed. Remove the torch and
check the tip of the torch's center orifice.
