Your 6820 User Information Products
Available Learning Products The learning products for the Agilent Technologies 6820 Gas
Chromatograph (GC) consist of four manuals and a poster. Use
the poster as a guide during installation of your new
instrument. The five manuals are provided in a printable format
on the CD-ROM (part number G1176-90005) included with the
GC.
The easiest way to access the manuals on the CD is to insert it
into a computer CD drive, browse to the CD, and run the file
setup.exe. This installation program will put shortcuts in your
computer’s Start menu that will link to the manuals (either
copied to your computer’s hard drive or on the CD-ROM). In
Microsoft® Windows® 2000 and XP®, these shortcuts will be
installed in the following path (by default):
Start/All Programs/Agilent/6820 (XP)
Start/Programs/Agilent/6820 (2000)
Alternately, you can browse the CD-ROM, and open the files
directly.
Site Preparation and
Installation
The documents listed below are designed to quickly and easily
guide you through the process of installing and verifying the
performance of the 6820 GC.
Installation Poster
Start here. This poster provides an overview of the installation
process and summarizes important safety information about
the instrument. For each installation step, find detailed
instructions in the Getting Started manual.
Getting Started (this manual)
Read this during installation and setup. This guide provides
detailed site preparation information and the step-by-step
instructions you will need to:
1Prepare your working space
2Provide the appropriate GC supplies
3Install the GC hardware

8Getting Started
4Install the GC software (if using Cerity Chemical)
5Configure the GC for use
6Verify that the GC is working properly
By following these steps you will also learn some simple but
important operating tasks that you will perform frequently.
Daily Use and Operation Operation
This guide provides all supplemental information and
procedures needed for everyday GC operation. Read the
Operation manual to learn:
• Important GC features
• How to use the controls to run samples
• How the GC provides feedback to you about its performance
• How to program analysis settings
• How to program the 6820 to automate tasks
• How the GC components (inlet, detector, column oven, etc.)
can impact your analysis
• How to configure the GC when changing or modifying
hardware
• How to safely shut down the GC when not in use
• How to work safely when using the electron capture detector
by using highly recommended safety precautions

When You Need More
Information
When you are ready to learn more about your instrument or if
the instrument is in need of maintenance, refer to the following
manuals as needed. The information in them is arranged so that
you can learn at your own pace, reading only the information
you need.
Maintenance and Troubleshooting
This manual provides troubleshooting information and
procedures, and also step-by-step maintenance procedures. It
describes:
• What error messages mean and what to do about them
• Chromatographic troubleshooting techniques
• How to replace consumable items, such as inlet liners and
septa
• How to perform simple performance enhancement
procedures, such as detector thermal cleaning
• How to diagnose and resolve certain hardware-related
performance and operating problems

10 Getting Started
In This Guide…
This document is concerned with installing the 6820 Gas
Chromatograph (the GC) in your laboratory, connecting it to
your data recording or processing equipment, and verifying that
it is operating correctly.
1 The 6820 Gas Chromatograph
A general description of the GC appears in this chapter. It
includes general warnings (heat, shock, etc.) that apply to the
entire GC.
2 Site Preparation
This chapter describes the things you must do (or have done)
before installing the GC in your laboratory.
3 Installing the GC
This chapter contains installation procedures for the GC. Most
of the steps apply to all GC systems. Some are optional, such as
plumbing for valve actuator air.
4 Preparing for Operation
Before checking the performance of your GC, perform the
preliminary steps described in this chapter.
5 Checking Performance
To check the performance of your GC, run the sample mixture
for your detectors as described in this chapter.
ASwagelokConnections
The GC and gas tubing use many Swagelok fittings. If you are not
familiar with Swagelok connections, review these procedures.
B Factory Plumbing
The factory standard plumbing designs—how you may expect
the GC to be plumbed when you unpack it—appear here.
