HFBA = heptafluorobutyric anhydride; TFECF = 2′,2′,2-trifluoroethyl chloroformate; PFPA = pentafluoropropionic anhydride.
GC-MS = gas chromatography-mass spectrometry; LC-MS = liquid chromatography-mass spectrometry.
Reported as limit of quantification (LOQ) = 5 nmol/l = limit of detection (LOD) × 1.5 [27], and LOD (μg/l) calculated as follows: 5 nmol/l ÷ 1.5 × 1 mol/109 nmol × 116.21 g/mol × 106 μg/g = 0.4 μg/l.
