Manuals, Information, Tools and Where to Find Them
This manual describes how to operate the 8355 SCD and the
8255 NCD as installed on an Agilent 7890B Gas Chromatograph
(GC). This manual also provides operating recommendations,
maintenance procedures, and troubleshooting. For installation
instructions, see “Overview of Installation and First Startup” on
page 14. To prepare the installation site for a new SCD or NCD,
see the Agilent 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.
