New peak detection (NPD) is a significant component of the multiattribute method (MAM) for MS use to facilitate the detection of quality attributes exhibiting abnormal ratio changes, vanishing attributes, or newly emerging attributes. However, challenges remain to get a balanced sensitivity and minimize false positives in NPD. In this study, we have developed a robust NPD and identification method to enhance sensitivity 10-fold (0.
