Setting up the Hardware

Important: If either component (pressure sensor or controller) is replaced, the
system may need to be re-zeroed.
Special Hardware Considerations
MSD Configuration for low-mass (hydrogen or helium) detection
The standard Agilent 5977 MSD is not designed to detect low-mass species like Hydrogen or
Helium since these species are typically the carrier gases used in GC/MS applications. In order to
detect low-mass ions, the MSD ionization source must be modified to use a special low-gauss
magnet and an ultra-wide draw-out plate. These parts are included with the 5000B RTGA kit and
may have been installed in the MSD at the factory or onsite during installation of the RTGA system.
You can confirm this by reviewing the
Installation and Configuration Data Sheet that was provided
with the RTGA documentation. If you have any questions about the configuration of your RTGA as
it was shipped form the factory, please contact Diablo Analytical.
Converting the MSD from RTGA to GC/MS
The Agilent 5977 MSD used in the Diablo 5000B RTGA can also be used in a standard GC/MS
configuration by adding the appropriate Agilent Technologies Gas Chromatograph. To convert from
RTGA operation to GC/MS operation, you simply vent the MSD, remove the RTGA interface
assembly from the MSD and replace it with the standard GC/MS interface that is included with the
system. Please contact Diablo Analytical for more information on reconfiguring your RTGA for use
as a standard GC/MS.
