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.
