The AX-80 mass spectrometer system can be configured to meet most
Residual gas
analysis and process monitoring applications. With mass ranges of 80amu and a choice of detector systems the
AX-80 may be supplied as an
"add on" to an existing vacuum system or as a complete stand
alone unit with integrated vacuum and inlet system. The AX-80 uses a PC
Computer as its system controller and its operating software is written in
a high level language. This simplifies updating, and allows easy
customising to meet specific process requirements. The user-friendly
software operating under 'Windows' make the AX-80 easy to use in all RGA
and gas analysis applications.
Key Benefits
 | Low Cost |
| Small Size |
| Simple to use |
| Comprehensive Software. |
Complete RGA.
|
The Analyser.>
The quadrupole analyser is available with a choice of ion sources,
mass filters and detection systems. The standard ion source is a
radially symmetrical design fitted with twin filaments and suits most
applications. The standard filaments are tungsten but thoria coated
iridium are available if required.

^The Electronics Unit.
This compact unit contains the complete quadrupole electronics and
plugs directly onto the analyser. Communication with the PC Computer is
via the RS232.
The unit has a performance and features only found on more expensive
RGA's, and yet its small size and low cost is achieved by the use of the
very latest electronic techniques. |
|
Software features
The new 'Windows' RGA software for the AX-80 mass spectrometer has
been designed to be 'user friendly' and very simple to learn and use.
