Fig. 8. Overlay of full HReMS chromatograms and extracted ion chromatograms filtered on the accurate mass of leucoindigoidine from the governing liquid (GL) samples. In the upper panels are reported (1) the full mass chromatogram and (2) the extracted ion chromatogram filtered on the accurate mass of leucoindigoidine (m/z 1⁄4 251.0781) of 3 kDa GL filtrate of the samples inoculated with Pseudomonas fluorescens 84095 (trial C). In the lower panels are shown the full scan MS (3) and extracted ion (4) chromatograms referred to the analysis of the inoculated and pepsin-digested bovine lactoferrin (LFH) treated samples (trial D).
