PlasmaQuant MS product family

2.5.6
Safety instructions relating to the formation of ozone and toxic vapors
The interaction between the UV radiation from the plasma and the surrounding air
results in the formation of a high concentration of toxic gases such as ozone and
nitrogen oxides.
Observe the following notes:
The PlasmaQuant MS may only be operated with an active exhaust unit.
The exhaust unit must be switched on before igniting the plasma.
2.5.7
Safety instructions relating to compressed gas containers and systems
The principal gas used by the PlasmaQuant MS is argon. The only gases to be used in
the integrated Collision Reaction Cell (iCRC) are hydrogen and helium. The
PlasmaQuant MS is also fitted with N
2
or O
2
connections for the Nitrox option. Do not
connect any other gases than those specified to the correct inlet fittings.
Observe the following notes:
Gases are taken from compressed gas cylinders or local liquid gas systems. The
required purity of the gases must be ensured.
Work on compressed gas cylinders and systems must only be carried out by
individuals with specialist knowledge and experience in compressed gas systems.
For compressed gas operation, the safety instructions and guidelines which are
valid at the operating location must be strictly complied with.
Cylinders must be used and stored only in a vertical position and secured to an
immovable structure or a properly constructed cylinder stand. Move cylinders only
by securing them to a properly constructed cart.
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 damages must be repaired
immediately.
Any leak (except that of air or oxygen) can result in an oxygen-deficient
atmosphere which can cause asphyxiation. The area in which cylinders are stored
and the area surrounding the instrument must be adequately ventilated to prevent
such gas accumulations.
The gas supply must be closed prior to servicing and repairs.
After successful repair and servicing of components of the compressed gas
containers or system, the device must be checked for sound operation prior to
recommissioning.
PlasmaQuant MS instruments may be used with hydrogen gas in the iCRC system.
Appropriate safety precautions must be taken, as Hydrogen is combustible over a wide
range of concentrations. A hydrogen fire may be invisible under bright ambient light.
The temperature increases with gas expansion, and if it is allowed to expand rapidly
from high pressure, hydrogen gas can self-ignite.
