Figure 2From: A simple peak detection and label-free quantitation algorithm for chromatography-mass spectrometryThe principle of the AB3D XIC peak detection algorithm. For local maximum peaks A and D, B-A-C and C-D-C’ were picked as two candidate peaks when a horizontal line was drawn at 50% of the highest intensity (a), while B-A-C’ were picked as one candidate XIC peak when a horizontal lines was drawn at 30% of the top intensity (b).Back to article page
