Operating in Electron Ionization (EI) Mode
Operating the MSD from the Data System
The Agilent MassHunter Data Acquisition Workstation automates tasks such
as pumping down, removing the ion source, monitoring settings, setting
temperatures, tuning, and venting the MSD. These tasks are described in this
chapter. Additional information is described in the manuals and online help
supplied with the MassHunter Workstation software.
The software and firmware are revised periodically. If the steps in these procedures do
CA UT IO N
not match your MassHunter Workstation software, refer to the manuals and online
help supplied with the software for more information.
Operating the MSD from the LCP
The local control panel (LCP) shows the status of the MSD or initiates a task
on the MSD without using the Agilent MassHunter Data Acquisition software.
The Agilent MassHunter Data Acquisition software may be located anywhere
on the site local area network (LAN), so the Data Acquisition software might
not be near the instrument itself. Because the LCP communicates with the
Data Acquisition software through the LAN, you can access Data Acquisition
software functions, such as tuning and starting a run, right from the MSD.
Only certain features are available from the LCP. The Data Acquisition
software is the full-featured controller for most instrument control operations.
Modes of operation
The LCP has two modes of operation: Status and Menu.
Status mode requires no interaction and simply displays the current status of
the MSD instrument or its various communication connections. If you select
[Menu], then [No/Cancel], you will be returned to the Status mode.
Menu mode allows you to query various aspects of the GC/MSD and to initiate
some actions like running a method or sequence, or preparing to vent the
system.
