Behavior in case of ring plasmas
The manual plasma deactivation switch is located on the left-hand side of the device (red).
In the following situations, press the deactivation switch without delay to prevent the torch
from melting:
−
The plasma produces loud noises (rattles).
−
The shape of the plasma changes considerably and a shining ring is visible on the
inside of the coil.
−
Torch parts begin to glow.

Safety instructions relating to the formation of ozone and toxic vapors
The interaction between the UV radiation from the torch and the surrounding air results in the
formation of a high concentration of toxic gases such as ozone and nitrogen oxides.
Additionally, toxic byproducts may escape from the samples and during sample processing.
Observe the following notes:
The PlasmaQuant PQ 9000 may only be operated with an active exhaust unit.
The exhaust unit must be switched on before igniting the plasma.
2.6.7
Safety instructions relating to compressed gas containers and systems
Observe the following notes:
Argon is taken from compressed gas containers or local liquid gas systems. The required
purity of the gases must be ensured.
Work on compressed gas containers and systems must only be carried out by individuals
with specialist knowledge and experience in compressed gas systems.
For compressed gas container or gas plant operation, the safety instructions and
guidelines which are valid at the operating location must be strictly complied with.
High pressure hoses and pressure reducers may only be used for the assigned gases.
All pipes, hoses and screw connections must be checked weekly for leaks and externally
visible damage. Possible pressure losses from closed systems and lines under pressure
must be determined. Leaks and damaged must be repaired without delay.
The gas supply must be closed prior to servicing and repairs!
After successful repair and servicing of the components of the compressed air containers
or system, the device must be checked for sound operation prior to recommissioning!
Independent assembly and installation are not permitted!
