RGA Quadrupoles

The New Generation Micropole^TM RGA has arrived !

 

The Micropole™ Residual Gas Analyzer is one of the smallest complete mass spectrometer systems available. The compact size is achieved by the patented design of miniature array of quadrupole mass filters. The array offers similar or greater sensitivity than conventional mass spectrometers but in a fraction of the volume. The system is capable of operating at much higher pressures than traditional systems, so the need for additional differential pumping equipment is reduced.

 

The sensors are factory pre-tuned and calibrated against transfer standards which allows direct interchangeability of the sensor by the user without the need for technical expertise to calibrate.

It is possible to take data without a PC when you use the Monitor Controller with 3.5” LCD. Up to eight Micropole systems can be networked and controlled using RS-485 or Ethernet communication.

 

Product Features

•  Extremely compact size and lightweight

1/20^th size when compared to conventional residual gas analyzers makes it easy to integrate to your system.

• High performance

Mini array of 9 quadrupoles gives excellent sensitivity at a fraction of the volume of traditional quadrupoles.

•  High pressure operation

Can be used at up to 0.9Pa (7mTorr, 9 x 10^-3mbar) so in many applications in many application the need for expensive vacuum pumping is reduced or eliminated.

• Interchangeable Sensor Head in calibration

The sensor heads are pre-tuned and calibrated prior to shipment allowing the user to make sensor changes in the field without the need for fine tuning or technical expertise.

•  Network Sensors

Up to eight sensors can be monitored by a single PC using RS-485. The systems can also be monitored remotely over Ethernet.

•  User friendly software

Micropole Scanner™ software allows the user to monitor partial pressures of gases in various modes e.g. trend graph, analog graph, leak mode, bar graph, 3D…

• Monitor Controller

The optional Monitor Controller can be used on the chamber mounted directly on the Spectrum Generator, allowing the user to monitor the vacuum chamber without the need for a PC.

As an integral part of the vacuum equipment, the Micropole^™ qualifies tools for process and provides real time control of vacuum processes. By increasing tool uptime and reducing scrap products the Micropole^™ helps improve productivity in manufacturing facilities. Typical applications of the Micropole^™ mass spectrometer RGA : Semiconductor Wafer Fabrication - Physical Vapor Deposition - Magnetic/Optical Storage Media - Industrial Vacuum Processes - Vacuum Research and Development - Glass/Optical Coating - Particle Accelerators.

 

The Micropole^™ can double up as an on board helium leak detector and by using extra quadrupole heads can be used on other vacuum systems in the vicinity without breaking vacuum on the chambers it is mounted to. It is an economical way to have a leak detector capability that can be shared among several labs.
