Response to Comment on 'HILIC-NMR: Toward the Identification of Individual Molecular Components in Dissolved Organic Matter'

摘要

We thank Dr. Blough and Dr. Del Vecchio for their comments.1 The authors very much agree that these signals are not due to the fluorescence of the model quinones used but that instead that the components indicated are somehow affected by quinones as the fluorescence intensities are altered by quinone addition without changing loadings (i.e., excitation and emission spectra). We further apologize for not expressing this more clearly as well as not clarifying a particular sentence in the text. "Correlation data indicate that all quinones..."2 should more specifically read "Correlation data indicate that all quinone-influenced signals." Taken out of context this sentence is certainly misleading but the remainder of the text utilizes the phrase "quinone-influenced" and the authors have clearly stated that "quinones are not attempted to be identified" with this parallel factor analysis (PARAFAC).2
