Troubleshooting the MSD
This chapter is a quick reference to symptoms and possible causes of the
most common problems experienced by the HP 5973 Mass Selective Detec-
tor (MSD). Related symptoms are grouped in these categories:
• General symptoms
• Chromatographic symptoms
• Mass spectral symptoms
• Pressure symptoms
• Temperature symptoms
• Error messages
• Contamination
• Air leaks
For each symptom, one or more possible causes are listed. The possible
causes listed are not in a strict order. In general, however, the possible
causes listed first are the most likely causes
or the easiest to check and
correct.
This section is only a quick reference. No corrective actions are listed for
the possible causes for each symptom. For more extensive troubleshooting
information, see the Troubleshooting (HP 5973 MSD) section in the online
help of the MSD ChemStation software. The online troubleshooting pro-
vides more explanation and, in many cases, corrective actions.
