The Hewlett-Packard HP 1046A is a stand-alone fluorescence, phosphorescence, and chemiluminescence detector designed to connect with high performance liquid chromatographs. It features a functional keyboard and a 32-character vacuum fluorescent display for user interaction.
This document serves as a technical guide for service personnel, offering detailed hardware descriptions of internal boards such as the Fluorescence Detector Controller Board (FOC) and Photomultiplier Power and Control Board (PPC). It includes illustrated part breakdowns, replacement procedures for components like the grating assembly, and a comprehensive diagnostic section covering troubleshooting and performance check-outs.
The instrument must be turned off for at least 5 minutes to allow high voltage on capacitors to dissipate.
