Bayard-Alpert Ionization Gauge Controllers

T

he Granville-Phillips Model 330 Ionization Gauge

Controller is reliable, easy to operate, easy to service and

moderately priced. The 330 with switchable, variable

emission currents provides the advantage of long filament life,

excellent immunity to electrical noise and easily read pressure

display.

Bayard-Alpert style gauges have become the standard for

accurate measurement of vacuum in mass spectrometers.

In some

instances, a mass spectrometer may be shipped without a vacuum

gauge since it is an optional accessory (such as in the Agilent

Technologies 5971 Mass Spectrometer). The mass spec user can

easily add the controller at a cost significantly less than purchasing

directly from the mass spectrometer manufacturer.

Often the user may want to add additional gauges to better

visualize the operation of the mass spectrometer. On magnetic

sector instruments or other mass spectrometers where the source

and analyzer are differentially pumped, two ion gauge controllers

would be advantageous to separately monitor the vacuum in both

the source and at the analyzer (multiplier section). This will enable

the quick diagnosis of pumping and vacuum problems for optimum

instrument performance and maximum electron multiplier life.

An Ion Gauge Controller can easily be added to the Agilent

Technologies 5971 mass spec as shown on the right, by inserting

the Ion Gauge Adapter between the NW25 flange on the mass spec

and solenoid valve/calibration vial. The Ion Gauge Adapter

contains NW25 flanges on both ends to clamp into the Agilent 5971

as shown, and a 3/4" Cajon 'O' Ring fitting to attach the ion gauge

tube. Also included with the Ion Gauge Adapter is one centering

ring, and one clamp. A complete set up for the Agilent 5971 as

shown would include one of each of (1) Model 330 Ion Gauge

Controller, (2) Ion Gauge Adapter, (3) G75K Part #G75K—Click for details
