“…Neurotransmitters are hard to be detected because they exist at extremely low concentrations in biological samples; therefore, specific and very sensitive bioanalytical methods are required (Bicker et al, 2013). For this reason, solid‐phase microextraction is often used for sample purification and enrichment (Lefeuvre et al, 2021). In this paper, the precolumn derivatization method was adopted.…”

“…Most studies involving absolute quantitation are carried out using targeted assays, most often triple quadrupoles in multiple reaction mode 5 , 6 , 7 , 8 where accurate and robust quantitation can be achieved by choosing selective transitions with optimized instrumental parameters. Absolute quantitation can also be performed through less targeted analyses, using high‐resolution mass spectrometry, 9 , 10 , 11 , 12 such as quadrupole‐time‐of‐flight or orbitrap‐based systems. In these cases, data are acquired in an untargeted manner, and selective data processing allows peaks of interest to be filtered out for further analysis.…”

“…The analysis of catecholamines has been performed with reversed‐phase (Bergh et al, 2018) and hydrophilic interaction liquid chromatography (Aturki et al, 2011) or weak cation exchange chromatography in mixed mode (Lefeuvre et al, 2021). In addition to liquid chromatography (LC), gas chromatography (GC) and capillary electrophoresis are also possible separation methods (Tsunoda, 2006).…”

“…Regarding fluorescence, chemically induced fluorescence (after derivatization with luminol or peroxyoxalate) enhances the fluorescence signal and sensitivity of catecholamines, allowing determination in real samples (Tsunoda, 2006). In addition to these detectors, tandem mass spectrometry coupled to HPLC is a robust option to determine the catecholamine content in real samples, as the mass spectrometry (MS) detector has a high selectivity that allows analytes and matrix interferents to be distinguished based on their masses (Lefeuvre et al, 2021). Extraction protocols used in these methods vary from solid‐phase extraction (SPE) on a cation‐exchange column (Takezawa et al, 2000), C 18 cartridges (Talwar et al, 2002) and aluminum oxide columns (He et al, 1997; Li et al, 2000) to liquid–liquid extraction (Dikunets et al, 2020).…”
