Chromatographic Peak Integration Study Guide
School of Analytical Chemistry · Advanced Analytical Chemistry · Intermediate
Open full lessonLearning objectives
- Explain the purpose of peak integration.
- Describe how baseline placement affects area.
- Distinguish peak area from peak height.
- Recognize common integration challenges.
- Explain when reintegration may be justified.
- Describe data-integrity expectations for integration.
Executive summary
Peak integration converts detector signals into numerical values.
The software must determine:
- where a peak begins,
- where it ends,
- what baseline lies beneath it,
- how much detector response belongs to that peak.
Because quantitative calculations often depend on peak area, integration directly affects reported results.

Key takeaways
- Integration converts chromatograms into quantitative data.
- Baseline placement is critical.
- Automated integration requires review.
- Reintegration must be justified and traceable.
- Poor separation cannot be corrected mathematically.
- Area percent depends on method and processing choices.
Self-review questions
