About the Clarus GC/MS System

61

TurboMass Software

TurboMass software is the user interface of the Clarus system. The following
screens show some examples of how you can control Clarus. Interaction is via the
mouse and keyboard using menu-driven commands. Printing, file management and
other routine procedures are performed using the appropriate Microsoft Windows
modules.

Top Level Screen

This screen contains the GC/MS status, sample list, sequence queue, and provides
you with access to all other functions.

Tune Page

The Tune Page allows you to tune the mass spectrometer, control the gases, set the
GC interface temperature, and monitor the instrument vacuum pressure.
