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.

  1. Select the rider peaks you want to separate on the leading side of the mother peak: use Chromatogram - Baseline - Front Tangent or icon .
  2. Select the rider peaks you want to separate on the trailing side of the mother peak: use Chromatogram - Baseline - Tail Tangent or icon .
  3. 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.
