Manuals, Information, Tools and Where to Find Them

This manual describes how to operate the Agilent 8355 Sulfur

Chemiluminescence Detector (SCD) and the Agilent 8255

Nitrogen Chemiluminescence Detector (NCD) as installed on an

Agilent 7890B Gas Chromatograph (GC). This manual also

provides operating recommendations, maintenance procedures,

and troubleshooting. For installation instructions, see the

Agilent 8355 SCD and 8255 NCD Installation and First Startup

Guide. To prepare the installation site for a new SCD or NCD,

see the Agilent 8355 SCD and 8255 NCD Site Preparation

Guide.

In addition, Agilent provides other manuals, familiarization

information, and help systems for self-paced learning about the

7890B GC. You will need to reference this general GC

information for installation and operation of the detector. The

sections below describe this information and where to find it.

GC Manuals, Tools, and Online Help

Agilent provides several learning products that explain how to

install, operate, maintain, and troubleshoot the 7890B GC

system. These manuals can be found on the Agilent GC and

GC/MS User Manuals & Tools DVDs that are included with your

GC shipment.

Installing your manuals provides for a much richer user

experience by providing the ability to install the manuals you

want, in the language you want. Install HTML and PDF versions.

environment), gas and reagent gas

purity, gas supplies, gas plumbing

(including filters, regulator types, and

tubing needs), and cryogenic cooling

supplies (if used).

Recommended supplies to purchase

before installation.

•Before installation, to prepare the

laboratory site.

•Before installation, to find what

supplies are needed for successful

installation (such as gases,

installation kits, gas purifiers,

regulators, tubing, fittings,

consumable parts, and so on).

•At any time, to refer to expected

requirements for gas supplies,

regulators, cryogenic cooling

supplies, supply pressures, and so

on.
