About This Manual

This manual contains information for operating and

maintaining the Agilent 5977 Series Mass Selective Detector

(MSD) systems.

1 “Introduction”

Chapter 1 describes general information about the 5977 Series

MSDs, including a hardware description, general safety

warnings, and hydrogen safety information.

2 “Installing GC Columns”

Chapter 2 shows you how to prepare a capillary column for use

with the MSD, install it in the GC oven, and connect it to the

MSD using the GC/MSD interface.

3 “Operating in Electron Ionization (EI) Mode”

Chapter 3 describes basic tasks such as setting temperatures,

monitoring pressures, tuning, venting, and pumpdown. Much of

the information in this chapter also applies to CI operation.

4 “Operating in Chemical Ionization (CI) Mode”

Chapter 4 describes additional tasks necessary to operate in CI

mode.

5 “General Maintenance”

Chapter 5 describes maintenance procedures common to both

EI and CI instruments.

6 “CI Maintenance”

Chapter 6 describes maintenance procedures unique to CI

MSDs.

1Introduction

5977 Series MSD Version

5977 Series MSDs are equipped with a high performance turbomolecular

(turbo) pump or a diffusion pump, and a choice of three foreline pumps. In

addition, there are two types of analyzers (stainless steel or inert) and four

types of ion sources. The serial number label displays a product number

(Table 1) that indicates what type of MSD you have.
