2.3 Instrument Overview
A diagram of the major HAPSITE ER components is shown in Figure 2-1, including
the pumps used to provide flow and vacuum. Service Module components are also
identified in Figure 2-1. Service and HAPSITE Modules contain a Vacuum
Interconnect Valve and electrical connectors through which vacuum systems join.

2.4 Description of Subsystems
HAPSITE combines two analytical techniques, gas chromatography and mass
spectrometry, to separate and identify the organic components in a gas phase
sample. The HAPSITE software also allows for the quantification of analytes.
HAPSITE is comprised of the following subsystems:
 Gas Chromatograph, see section 2.4.1
 Mass Spectrometer, see section 2.4.2 on page 2-5
 Vacuum System, see section 2.4.3 on page 2-6
 Electronic Systems, see section 2.4.4 on page 2-7
 Software Systems, see section 2.5 on page 2-8
2.4.1 Gas Chromatograph
Gas Chromatograph (GC) performs a time separation of the sample compounds.
The separation order is primarily based on the volatility of the sample components.
HAPSITE ER GC system utilizes nitrogen as the carrier gas to transport analytes
through a column, of which the standard column is a narrow-bore fused silica tube
15 meters in length. The carrier gas is referred to as mobile phase. The inside of the
column is coated with a thin layer of a material known as stationary phase.
