11.2 Common Chromatographic and Method

Problems

This section provides additional information to help diagnose common operational
problems. It is divided into two topics:

1 Chromatographic Problems
2 Method Problems

If the issue is not resolved after taking the suggested measure(s), contact INFICON.

11.2.1 Chromatographic Problems

Unexpected chromatographic behavior may be the result of:

• Electronic or mechanical failure
• Contaminants in gas lines, injectors, columns, and detectors
• Incorrect or inappropriate set points
• Leaks, bleed, or other chromatographic difficulties

These conditions often interact. For example, baseline problems may arise from any
combination of the conditions. Accordingly, this section is organized by symptoms with
reference to the most probable causes.
