Introduction Networks are pervasive across various scientific disciplines. Social networks model human relationships and interactions, while neural networks represent cognitive processes (Cacioppo et al., 2019). Food webs depict ecological feeding interactions (Dunne et al., 2002), and electrical networks connect components within engineered systems (Barabási, 2002). The internet exemplifies a global network linking users worldwide.

3.3.1. Limits of quantification, linearity ranges and instrumental precision Regarding iLOQs, pH=3 turned out to be more sensitive than pH=7 as can be seen in Figure 3, specially for neutral PMOCs although they were not retained at any condition. Cationic compounds rendered iLOQs below 0.5 ng/mL in all the cases except for tetrapropylammonium in the P2 column at pH=7, which was 2.2 ng/mL.
