Baseline estimation is a major component to providing accurate integration for peak areas. Baseline estimation can be done from the Summary Tab by right-clicking the sample in the Sample Window or directly within the chromatogram window.
Note: To estimate ALL ions in a GCMS sample, estimate the baseline by right-clicking the sample in the Sample Window of the Summary Tab.
Parameters
- Search Window Width: Use a wider search window to get smoother baseline if peak shoulders are present.
- Optimize Baseline: Activates the advanced optimization parameters.
- Slope Smoothing Factor: Higher values generates smoother baseline.
- Slope Tolerance: Increase slope tolerance to allow local convex shapes in the baseline.
- Minimum Abundance: Set the minimum abundance of the chromatogram to ignore the intervals with no detector signals.
