Metabolomics analysis, performed via UPLC-QTOF/MS, and fatty acid analysis, conducted via GC鈥揗S, employed, and the results demonstrated a significant increase in antioxidant activity of post-roasting and in vitro digestion, ranging from 1.16 to 3.44 times. Untargeted metabolomics identified a ...
3.8. LC-QTOF-MS and GC–MS profiling For further phytochemicals exploration, out of six samples under study, the phytochemically rich sample i.e., SA-03 was opted for LC-MS and GC–MS profiling. The GC–MS chromatogram of SA (i.e., SA-03) methanolic extract exhibited more than ten ...

along with robust nominal mass GC/MS and triple quadrupole mass spectrometry. Researchers will have at their disposal pairings of time-tested nominal mass systems as well as industry-leading high performance GC-TOF and LC-QTOF MS systems. The application support...
OPLS-DA score plots for discriminating the urine metabolome from control group and treatment group and corresponding permutation test obtained from GC-MS. (a) CONvsASG group, (b) CONvsAMG group, (c) ASGvsAMG group. Chance permutation at 200 times was used for the discrimination between (d)...
A modified QuEChERS technique was followed for estimation of fipronil (5% SC) in paddy ecosystem using GC-ECD and confirmation by GC-MS/MS. The initial residues (0.168–0.794 μg g−1) of total fipronil i.e., sum of fipronil and its metabolites (viz., desulfinyl and sulfone) in leaf...
3.2. HS-SPME-GC-O-QTOF analysis of scallops treated by different drying methods 3.2.1. Statistical classification analysis of VOCs HS-SPME/GC-TOFMS was used to obtain the total ion flow diagrams of the five scallops treated by different drying methods, as shown in Fig. 3A. There were obvi...
12 7200 Accurate-Mass QTOF Operation Manual Introduction 1 Vacuum gauge The 7200 Q-TOF GC/MS is equipped with four ion vacuum gauges. The MassHunter Workstation can be used to read the pressure (high vacuum) in the vacuum manifold, the turbomolecular vacuum pump discharge, and the flight ...
