Their high resolution is useful for determination of charge state and protein mass measurements in addition to accurate mass determination of biological The Agilent QTOF 6540 is equipped with exchangeable ESI/APCI ion sources. The ESI source is the JetStream source. The instrument is capable of MS and MS/MS and it is using MassHunter software for data acquisition and processing. LC pumps can handle up to 8000 psi. Mass Accuracy of better than The X-series QTOF MS Systems are powered by the SCIEX OS user interface for simplified ease-of-use and streamlined data acquisition and analysis – it has never been easier to screen for unknown compounds, metabolomic analysis or performing biotherapeutic characterization.

Abstract Background Isodon lophanthoides, I. lophanthoides var. graciliflorus and I. serra are the three botanical sources of Xihuangcao, which are often used indiscriminately in herbal products. The aim of this study was to develop a rapid and accurate analytical method to identify the three different botanical sources of Xihuangcao by combining UPLC-ESI-QTOF-MS with chemometrics analysis Methods: An LC-PDA-MS/MS method was established by using acetonitrile-0.2% ammonium acetate as the mobile phase with gradient elution on a BDS Hypersil C 18 … Speaker: Damià Barceló, Ph.D., CID-CSIC Centre d’Investigació i Desenvolupament QTOF MS/MS for research.

Time-of-flight mass spectrometry is a method of mass spectrometry in which an ion's mass-to-charge ratio is determined by a time of flight measurement. Ions are accelerated by an electric field of known strength. This acceleration results in an ion having the same kinetic energy as any other ion that has the same charge. The velocity of the ion depends on the mass-to-charge ratio.

In this study, metabolites were identified in 13 post-mortem urine samples using liquid chromatography quadrupole time-of-flight mass spectrometry (LC-QTOF-MS). RapidFire User meeting Nov 14th 6. Operational Modes: MRM. MRM - A mass selected precursor ion is chosen with Q1 and the collision cell generates fragment ions. The fragment ions are then analyzed using selection of product ions with Q3. Specific mass passes through quad Collision energy applied. The QTOF-MS instrument was operated with an electrospray ion source ESI+ Agilent Jet Stream Technology in positive ionization mode, a quadrupole for isolation of precursor ions with a mass window of 1.3 or 4 m/z in MS-MS mode, a linear hexapole collision cell with nitrogen as collision gas at 0–40 eV collision energy, a TOF-MS with accuracy <3 ppm, mass resolution of 5,000–10,000 (100–922 m/z), a measuring frequency of 10,000 transients s −1 and a detection frequency of 2 GHz Workstation software facilitates processing of data generated by the Agilent LC-MS QTOF.

Application of LC/ESI-QTOF-MS in the Detection of Quinolones in Edible Animal Food Quinolones are a family of common antibacterial veterinary medicine which can inhibit DNA-gyrase in bacterial cells. However, the residues of quinolone in edible animal products may be directly toxic or cause resistant pathogens in humans.
