for more information. Quantitative identifications can be

made by analyzing standards of known concentration and creating a target
compound library of concentration response curves. See

Chapter 12, Target

Compound Methods

for more information.

In summary, the GC first separates the gaseous compounds by time. Then the MS
identifies and measures the gases contained in each of the time-separated peaks.
This enables the GC/MS system to report the specific identity and concentration of
each of the compounds present in the initial pulse of gas analyzed.

1.5 Instrument Overview

The HAPSITE system is comprised of two modules:

the HAPSITE, also known as the Analytical Module, and

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.
