Stanford RGA Residual Gas Analyser

Stanford Research Systems

The 100, 200 and 300amu residual gas analysers offer exceptional performance and value. These RGA's provide detailed gas analysis of vacuum systems at about half the price of competitive models. Each RGA system comes complete with a quardupole probe, electronics control unit (ECU) and a real-time Windows® software package that is used for data acquisition and analyis, as well as probe control.

Features:

  • 100, 200, and 300amu systems
  • Better than 1amu resolution
  • 6 orders of magnitude dynamic range in a single scan
  • 5 x 10-14 Torr detection limit
  • RGA Windows and LabVIEW software
  • Field-replaceable electron multiplier and filament
  • RS232 interface

Rugged Probe Design
The probe consists of an ioniser, quadrupole mass filter and a detector. The simple design has a small number of parts which minimises outgassing and reduces the chances of introducing impurities into your vacuum system. The probe assembly is rugged and mounts onto a standard 2 ¾" CF flange.

Compact Electronics Control Unit
The densely packed ECU contains all the necessary electronics for controlling the RGA head. It is powered by either an external +24VDC (2.5A) power supply or an optional, built-in power module which plugs into an AC outlet. LED indicators provide instant feedback on the status of the electron multiplier, filament, electronics system and the probe. The ECU can easily be removed from the probe for high temperature bakeouts.

Unique Filament Design
A long-life, dual thoriated-iridium (ThO2/Ir) filament is used for electron emission. Dual ThO2/Ir filaments last much longer than single filaments, maximising the time between filament replacement. Unlike other designs, Stanford filaments can be replaced by the user in a matter of minutes.
