Separating rider peaks by tangent
Rider peaks are small peaks which are not well resolved from a large and asymmetrical neighbor but sit on its leading or trailing side.
- Select the rider peaks you want to separate on the leading side of the mother peak: use Chromatogram - Baseline - Front Tangent or icon ⓐ.
- Select the rider peaks you want to separate on the trailing side of the mother peak: use Chromatogram - Baseline - Tail Tangent or icon ⓐ.
- You can check, modify the interval or delete this operations in the Integration Table (Baseline - Front tangent and Baseline - Tail tangent rows) ⓑ.
Note:
You can also use the Tangent Slope Ratio and Tangent Area Ratio from Chromatogram - Separation menu to set a threshold for the separation of rider peaks based on those two parameters.
