The liquid sample valve is externally mounted on the right side of the Oven Compartment and extends
through the isothermal oven, allowing direct injection. It is actuated by a solenoid valve located in the
Oven Electronics Compartment. The liquid sample valve captures a specific volume of liquid sample
below its bubble point, injects it into a temperature controlled (vaporizing) chamber of the LSV, which
then sends the vaporized sample into the oven.
1.4.2 Vapor version
The vapor version has a vapor input to the analysis, so it does not require a liquid sample valve. The
duration of an analysis cycle depends on the applications and consists of the following:
⎯ Carrier gas transports the vaporized sample through the columns.
⎯ The column then separates the components and passes them into the detector.
⎯ The detector measures the sample across the range of high to low concentration.
1.5 Class C oven
The Class C oven contains the same components as the Class B oven, but it has the capability to
handle more oven components. The Class C oven has a maximum of two detectors and a maximum of
six valves.
1.6 Oven with integrated controller
The oven with integrated controller can be either a Class B oven or a Class C oven. The distinguishing
feature is that an oven with integrated controller has the Single Board Computer (SBC) PCB installed
in the oven’s electronics compartment.
1.7 Air purge systems
The analyzer is suitable for a Class 1 Division 2 hazardous location, or an Ex Zone 2 area, without
purge and pressurization protection. Purge and pressurization protection of the electronics enclosure is
required for a Class 1 Division 1 location, or an Ex Zone 1 area. Refer to the analyzer nameplate for
purge and pressurization specifications.
1.8 System variations
This manual supports the basic PGC5000 Generation 2 analyzer. Section 9 presents additional
instruction for the PGC5000TPGC (temperature programmed GC). Section 10 includes information
about using the PGC5000A as a CAC replacement. For PGC5007 (fuel sulfur GC) and PGC5009 (fast
GC) information, see their respective manuals linked in the Additional information section.
2 Installation
WARNING – Bodily injury.
Before beginning installation, repair, or maintenance on the analyzer, contact the local Safety
Department to ensure that all safety guidelines, regulations and procedures are followed. This
includes obtaining the proper work permits.
The user is responsible for being familiar and complying with all safety and health guidelines,
regulations and procedures at the analyzer location. Consult Material Safety Data Sheets for
safety requirements.
When working on the analyzer, there is the possibility of exposure to hydrogen, nitrogen, and
other compressed gases. All appropriate precautions and extreme care should be taken when
working with all compressed gases.
Become familiar with the application specifications before working on the analyzer.
Wear protective clothing and equipment, such as rubber gloves and goggles or safety glasses
with side shields. Avoid contact with a hot surface during maintenance work on the analyzer
oven.
Before opening analyzer enclosure doors, be sure the area is safe from hazardous gases and
will remain so the entire time the analyzer is open.
