If you have an uninterrupted drying gas source (N2 generator) we recommend the you put the system into Standby. If you have an interrupted drying gas source (dewars) we recommend • Q-TOF mode (MS/MS) • Full spectrum of Product Ions (SIM-TOF) • With high resolution and accurate mass • Selectivity beyond any “triple quad” MRM method • Confirm TOF spectrum without interferences • High sensitivity structural elucidation tool Ideal tool for solving complex analytical problems The ultra-high performance liquid chromatography-quadrupole time-of-flight mass spectrometry (UHPLC/Q-TOF-MS) technique is a new approach in the chromatographic separations and has been successfully employed for fast, high resolution separations with required sensitivity. The Q-TOF (Quadruple-Time-Of-flight) HRMS mass spectrometer (Xevo G2-XS) contains the XS collision cell, StepWave TM ion optics and QuanTof technology to deliver superior sensitivity, selectivity, and robustness with mass accuracy, analysis speed, and dynamic range to provide comprehensive qualitative and quantitative information particularly for This report describes the evaluation of LC-QTOF-MS for the simultaneous full scan and MS/MS analysis for the detection and identification of 125 pesticides in tomato, zucchini, orange, leek, onion and lettuce. 2.

Jennifer M. Colby1, Katie L. Thoren2, Alan H. B. Wu1, Kara L. Lynch1 1Department of Laboratory Medicine, University of California San Francisco and San Francisco General Hospital, San Francisco, CA 94110 DATE: November 27, 2018 TIME: 8:00am PST. High-resolution, accurate-mass (HRAM) mass spectrometers (MS) are a class of MS instrumentation with capability to resolve complex sample matrix and to allow identification of compounds by measuring their accurate masses. Abstract The appropriate selection of quality marker (Q‐marker) for performing the comprehensive quality evaluation of traditional Chinese medicines (TCMs) has much more significance.
