AX200RGA

Residual gas Analysers

AX200 RGA

The AX-200 mass spectrometer system can be configured to meet most gas analysis and process monitoring applications. With mass ranges up to 200amu and a choice of detector systems the AX-200 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-200 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-200 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-200 mass spectrometer has been designed to be 'user friendly' and very simple to learn and use. For detailed information refer to the separate software leaflet.
