HAPSITE Smart Plus Operating Manual
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. It also contains 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 solid state memory and is located in the central
electronics assembly. The main processor accepts data from many points within
the system. It 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 touchscreen, keypad and display, the USB drive, the crossover cable
connection, the wireless connection, the hand control unit, the power and logic
connections to the Service Module, Headspace Sampling System, SituProbe 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 touchscreen, keypad, and other interfaces, and commands the operation
and sequencing of all the systems and subsystems. The analysis software
analyzes the data from the mass spectrometer, accesses the libraries as required,
and displays the results of the analyses on the front panel. The control software
allows a method to be started with minor modifications from the front panel. Design
or substantive modifications of the method require the use of the HAPSITE
Application software on an external PC.
The HAPSITE Application software, Plus IQ, is a Windows® XP and Windows®
2000 based system for use in the accessory Laptop. The Plus IQ software is used
to design and modify the methods under which the HAPSITE can operate, view the
data, analyze the results, and generate and print reports. The Laptop is linked to
the HAPSITE by a crossover cable or wireless connection, which permits
uploading of data from the HAPSITE and downloading new or modified methods to
the HAPSITE.
