INTRODUCTION
HP 5890 SERIES II GAS CHROMATOGRAPH
This section is intended to help the technician isolate problems to a specific component or compo-
nents. The HP 5890 Series II may be found in many different configurations, with varying component
options. This complicates the process of providing detailed troubleshooting procedures for even gener-
al problems. But, by using the general troubleshooting techniques presented here, along with the func-
tional diagrams found at the end of this section, successful results should be achieved.
There are five inlet options and six detector options which may be encountered when servicing an HP
5890 Series II Gas Chromatograph, as well as a wide variety of flow and pressure control components.
All of these common inlet and detector components are represented by the functional diagrams at the
end of this section. When troubleshooting inlets, detectors, and/or the flow/pressure systems, fold out
the page corresponding to the employed detector, while leaving the book open to the page corre-
sponding to the employed inlet. Maintenance procedures for most of the components are given in the
following sections. Procedures are supplied to remove, replace, and/or clean various subassemblies,
based on the current maintenance philosophy, i. e., to allow replacement of the lowest level compo-
nents applicable for a particular item.
Specific part numbers are not given in this portion of the service manual. For all replacement part num-
bers, refer to the IPB portion of this document.
This document is not meant to provide instruction for first time installation of any of the options dis-
cussed. The add-on sheets, which accompany the various options, exist for just this purpose, and
should be referenced when performing a first time installation.
