Figure 4.
A selected ion image of the precursor ion at m/z 140.1 (a), and the template used to apply the similarity measure (b). The top eight ion images matched with the precursor ion using hypergeometric similarity measure (c). Product ion spectrum obtained by UPLC-MS/MS used to validate the DetectTLC output (d). The fragment ions detected in both UPLC-MS/MS and DetectTLC datasets are indicated with red labels
