HAPSITE Smart Operating Manual
The diaphragm pump consists of four stages, in series. The diaphragm pump
draws the gas from the exhaust of the compound pump and compresses the
exhaust gas sufficiently to discharge the exhaust into the atmosphere.
1.6.4 Electronic Systems
The electronic systems in the HAPSITE are considered in four groups:
 Mass Spectrometer Control
 Gas Chromatograph Control
 Main Processor
 Interfaces
1.6.4.1 Mass Spectrometer Control
The mass spectrometer control electronics include the programmable DC and RF
power supplies for the mass selector, the DC power supplies for the filament, the
electron multiplier, the sputter-ion pump, and the A/D converter for the signal from
the electron multiplier.
1.6.4.2 Gas Chromatograph Control
The gas chromatograph control circuitry includes the power supplies for the
solenoid valves, the ovens, and the heated inlet line, and the control logic for all the
valves and heaters of the GC system.
1.6.4.3 Main Processor
The main processor is supported by a hard-disk drive, and is located in the central
electronics assembly. The main processor accepts data from many points within
the system, and controls all the other electronic sub-assemblies, both in routine
operation and in managing the data-taking methods.
1.6.4.4 Interfaces
There are several input/output devices within the HAPSITE. These include the front
panel keypad and display, the 3 1/2” floppy-disk drive, the crossover ethernet cable
connection, the hand control unit, the power and logic connections to the Service
Module, Headspace Sampling System, and the pins which read the details of the
gas mixture from the gas canisters.
1.6.5 Software Systems
The HAPSITE operates with two separate software systems. The instrument itself
incorporates control and analysis software. This control software accepts inputs
from the keypad and other interfaces, and commands the operation and
sequencing of all the systems and subsystems. The analysis software analyzes the
