can be heard, press the red plasma deactivation switch on the left side of the device.
Before the next ignition attempt, verify that the sample hose is immersed in the wash
solution and that the gas supply and the recirculating chiller are working properly.

The plasma ignites and the hose pump starts. The PlasmaQuant PQ 9000 is ready
for measurement after a brief plasma warm-up period.
ATTENTION!
Before plasma ignition, the following conditions are checked via internal safety circuits:
− Gas flow, cooling and exhaustion are switched on and comply with the specified
connection conditions.
− The torch is in working position.
− The plasma compartment door is closed.
If a fault is detected in one of the components the plasma will fail to ignite.
7.2 Switching off the PlasmaQuant PQ 9000
ATTENTION! Wait for the PlasmaQuant PQ 9000 to cool down before switching it
off!
After extinguishing the plasma, wait for at least 2 min. before switching off the device at the
power switch.
Switch off the PlasmaQuant PQ 9000 as follows:
1. After the end of analysis, allow wash solution to flow through the system for approx. 3 min.,
followed by water for 1 min.
Allow the device to run dry after this, until there is no more liquid in the hoses. If any hoses
need to be replaced, they will be drained of acid as a consequence!
2. To extinguish the plasma in the ASpect PQ program, click on in the toolbar.
Alternatively, use to open the P
LASMA
window and click on [P
LASMA OFF
].
3. Select the F
ILE

E
XIT
menu item and end the ASpect PQ program.
4. Confirm the query about switching off the purge gas for the detector with [Y
ES
] if the purge
gas should be switched off.
If work is only interrupted for a short period (up to 30 min.), do not switch off the purge gas.
This will save time during the ignition process until the detector is sufficiently purged.
5. Wait for the message stating that the device and the cooling can be switched off to appear.
6. Switch off the PlasmaQuant PQ 9000 and, if applicable, the automatic sampler at the
respective power switch.
7. Release the pump hoses at the PlasmaQuant PQ 9000.
− Release the pressure levers to ensure that the hose guide no longer exerts pressure
on the hoses.
− Pull the hose stoppers on the left-hand side of the pump from their lock.
8. In case the automatic sampler is used, release the pump hose in the same way as with the
hose pump on the PlasmaQuant PQ 9000.
9. Close the gas supply after switching off the devices.
