HAPSITE ER Operating Manual
1.5 Instrument Overview
The HAPSITE system is comprised of two modules:
 the HAPSITE, also known as the Analytical Module,
 the Service Module.
The HAPSITE is comprised of many systems and subsystems. Figure 1-1 shows
a diagram of the major subsystems. These subsystems include the several pumps
used to provide flow and vacuum.
The Service Module components are identified in Figure 1-1 , everything else is
housed in the HAPSITE. The Service Module and the HAPSITE module contain a
Vacuum Interconnect Valve and electrical connectors through which their vacuum
systems join. The modules communicate when the two modules are coupled
together.

1.6 Description Of Subsystems
The HAPSITE is comprised of the following subsystems:
 Gas Chromatograph, see section 1.6.1 .
 Mass Spectrometer, see section 1.6.2 on page 1-6 .
 Vacuum System, see section 1.6.3 on page 1-8 .
 Electronic Systems, see section 1.6.4 on page 1-9 .
 Software Systems, see section 1.6.5 on page 1-10 .
1.6.1 Gas Chromatograph
The HAPSITE’s GC system utilizes nitrogen as the carrier gas to transport analytes
through a column, a narrow-bore fused silica tube 15 meters in length, and then on
to the detector. The nitrogen is referred to as the mobile phase.
