Finnigan MAT Incos 50B Vacuum Measurement System

Easily mounts to Incos 50B Accurate Vacuum Measurement Bayard-Alpert Design Convenient Bench Top Enclosure

Model 330 Controller

Many Incos 50B mass spectrometers have been purchased without the optional vacuum measurement system. This leaves the user without any indication of the vacuum levels in the system and without information on possible system problems. Scientific Instrument Services is now offering a system for vacuum measurement on the instruments. This system consists of a Granville-Phillips Model 330 ionization gauge controller with Degas capability, cable, Bayard-Alpert ion gauge tube and a custom flange. The system easily mounts on the Incos 50B for accurate vacuum measurement. The custom manufactured flange bolts directly on the three studs in place of the solids probe flange. No modifications or changes to the mass spectrometer are required.

Ionization Gauge Flange and Ion Gauge Tube

The Granville-Phillips Model 330 ionization gauge controller utilizes a Bayard-Alpert style ionization gauge tube for accurate and convenient vacuum measurement. The 330 with switchable, variable emission currents provides the advantage of long filament life, excellent immunity to electrical noise and easily read green LED pressure display. It comes standard with degas capability.

The system is made to use a 3/4" tabulated Bayard-Alpert ion gauge tube. These tubes have become the standard for vacuum measurement in mass spectrometers.

The system includes the Model 330 Controller, a G75K ionization gauge tube with 3/4" Kovar arm, a 10' cable and one custom ion gauge flange.
