“…The concentration of H + in the mobile phase can affect the retention time, matrix effect, and the durability of the column, especially for pH values less than 6.0 [ 38 , 60 ]; an aqueous mobile phase with a pH of 6.9 allows a clear chromatogram with no matrix interferences to be obtained ( Figure 2 ).…”

“…To examine the precision in terms of repeatability, accuracy (trueness, %), and recovery of the developed method, canned tuna samples were spiked at five different concentrations of histamine (6.25, 12.5, 25, 50, and 100 mg/kg), and were analyzed over six successive days with three replications per day. The precision of the assay was determined by calculating the relative standard deviation (RSD, %) for the repeated measurements, and the accuracy of the method (trueness, %) was evaluated by assessing the agreement between the measured and nominal concentrations of analyzed samples [9,10].…”

“…As a consequence, countries such as the USA, through the Food and Drug Administration (FDA), and those of the European Union, by the Commission Regulation (EC) No. 2073/2005, have established regulatory limits for histamine levels in edible fish [8][9][10]. According to the FDA, a concentration of 50 mg/kg is an index of sample deterioration; thus, samples returning results at or above this level cannot be intended for sale or consumption.…”

“…Common methods for BAs determination are chromatographic ones, such as thin-layer chromatography (TLC), 6,7 capillary electrophoresis (CE), [8][9][10][11] gas chromatography (GC), [12][13][14][15][16] and high-performance liquid chromatography (HPLC). [17][18][19][20][21][22][23][24][25][26][27][28][29] HPLC is the most widely used because of its high resolution, sensitivity, efficiency, and reliability. Nevertheless, a single chromatographic approach to simultaneously determine mixture of BAs without derivatization is not feasible due to the lack of adequate chromatographic or absorption/uorescence properties.…”

“…Fluorescent reagents are widely used in the pre-column or post-column derivatization in high-performance liquid chromatography coupled with uorescence detection (HPLC-FLD), which dramatically enhances the sensitivity of the detection of BAs. 6-Aminoquinolyl-N-hydroxysuccinimidyl carbamate (AQC), 17,18 dansyl chloride (DNS-Cl), [19][20][21][22][23] 9-uorenylmethyl chloroformate (FMOC-Cl), 24,25 and O-phthalaldehyde (OPA) [26][27][28][29] are some popular derivatizing reagents used for the determination of BAs. AQC, DNS-Cl, and FMOC-Cl all have intrinsic uorescence and may generate uorescent by-products during the derivatization process, which complicates BAs' quantitative analysis.…”
