PlasmaQuant PQ 9000
The mains plug must be connected to a proper CEE power socket to ensure that the
device meets protection class I (ground connector). It may only be connected to power
sources whose nominal voltage is the same as that on the type plate of the equipment. The
protective effect must not be invalidated by the use of an extension line which does not
have a protective conductor (
→
section "Energy supply" p.20).
The PlasmaQuant PQ 9000 and its system components must always be switched off
before being connected to the mains.
Before opening the device, it must be switched off at the device switch and the mains
connector must be disconnected from the mains outlet! Any work on the electronics
(behind the device enclosure) may only be carried out by the service engineers of Analytik
Jena AG and specially authorized technicians.

Hazards caused by plasma operation
Plasma is extremely hot (up to 10,000 K) and it emits electromagnetic and UV radiation. The
induction coil is operated with 1500 V RMS and 40.68 MHz. High-frequency radiation and UV
radiation can cause serious injuries to skin and eyes. Contact with the torch (plasma torch)
shortly after operation will cause skin burns. An electrical discharge may also occur across
larger distances and cause fatal injuries, electrical shock and skin injuries.
Observe the following notes:
To ensure safe torch operation, you must not ignite the plasma unless the following
conditions are met:
−
The plasma compartment door is closed.
−
The torch is in working position.
−
Sufficient cooling is supplied.
−
The extractor device is connected and switched on.
−
Argon supply is ensured.
Note:
The above mentioned components are backed up by hardware safety circuits.
Unless the reliable functioning of these components is guaranteed, the plasma will not be
ignited or it will be extinguished automatically if a component reports a malfunction.
The safety circuits must not be bridged.
Before opening the plasma compartment door, extinguish the plasma in the ASpect PQ
program. To do this, click on the
button in the program toolbar.
Wait for the compartment to cool down for at least 5 min
and avoid touching any hot parts
of the torch and its environment immediately after extinguishing the plasma.
