a,b, HPLC chromatograms showing the separation of Ahx and linear Ahx2-7 (a) or ε-caprolactam (cyclic Ahx1) and cyclic Ahx2-6 (b) that were detected using FLD and DAD, respectively. The concentration of the indicated compounds is shown. For cyclic Ahx2-6, no standards were available preventing their quantification.
