Fore-line roughing pump XDS46i

Parameters

Properties

Protection class

I

Voltage

200-240 V

Frequency

50/60 Hz

Power consumption

0.52 VA

Weight

48 kg

The fore-line roughing pump is used as both the primary pump for the first vacuum

stage and as a fore-line pump for the two turbomolecular pumps on the second- and
third-stage vacuum chambers.

The PlasmaQuant MS supplies the fore-line roughing

pump with 200-240 V.
The vacuum pump is a floor-mounted pump, typically placed under or behind the
bench where the PlasmaQuant MS is located. The pump can also be located remotely

(up to 12 m away from the ICP-MS) for noise reduction, and this is also recommended
for Clean Room operation.

Some mass spectrometer benches may be fitted with a noise- and vibration-isolating

compartment to install the vacuum pump. If this is used, take adequate action to
prevent the pump from overheating.
The outlet of the pump has to be connected to an exhaust unit. If the pump is linked to

the exhaust unit for the PlasmaQuant MS, the suction device must be operated even if
the PlasmaQuant MS is in the energy-saving standby mode. Alternatively, a separate

suction device can be used.
For models SV40BI, the pump must be equipped with an additional oil mist filter if the
pump is linked to the exhaust unit for the ICP-MS.
Only use protection class I fore-line roughing pumps which have a power cord with

protective earth (PE).
Please refer to section "Maintenance and care" p. 96 for information on maintenance

and care of the fore-line pump.

4.1.7

Device layout and space requirements

The PlasmaQuant MS is a compact device conceived for table-top operation. The space

required is a function of all components needed for the measurement.
The autosampler is installed next to the base instrument. Between these two
instruments 30 cm of clearance is required to allow space for opening the interface

door. Additional space may be needed for a PC and possibly a printer. The PC and

printer may also be placed on a separate table.
The workbench must meet the following requirements:



The dimensions of the workbench for the PlasmaQuant MS and the autosampler

must be at least 1800 mm x 800 mm. The height of the bench should be chosen
according to ergonomic aspects.



The workbench must be capable of bearing a load of at least 220 kg.
