Abstract: 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. A methodology for the determination of 17 main cannabinoids by liquid-chromatography coupled with quadrupole time-of flight mass spectrometry (LC/Q-TOF-MS) was developed in this work. The separation of the cannabinoids was done with a C8 reverse-phase column and a mobile phase consisting of acetonitrile and water with 0.1% formic acid. The Premier™ Technology Platform The Q-Tof Premier is a hybrid orthogonal acceleration Time-of-Flight (oa-ToF) mass spectrometer that enables automated exact mass measurement of precursor and fragment ions to yield the highest confidence in structural elucidation and Methodology for detection of native (underivatized) amino acids (AA) in atmospheric aerosols has been developed. This article describes the use of LC-MS (Q-TOF) and microwave-assisted gas phase hydrolysis for detection of free and combined amino acids in aerosols collected in a Southeastern U.S. forest environment. Accurate mass detection and the addition of isotopically labeled surrogates Unlike any other exact mass MS/MS benchtop system on the market, Xevo QTof mass spectrometer from Waters Corp.

With simple workflows, robust hardware, and end-to-end balanced performance, the X500R QTOF is the first high resolution LC-MS/MS system designed for routine testing to deliver exceptionally reliable results.

A LC-MS-QTOF system was chosen to analyze samples following Lawal et al. (2016) with some modifications. By dissolving about 2 mg of each extract in 80% v/v ethanol, the sample aliquots were preapred. Accurately, 200 µL of the sample aliquot was filtered using microfilter and transferred into a glass vial. 2017-03-24 2005-08-05 LC–QTOF‑MS method. e analysis of all extracts was performed on Agilent1260 In nity HPLC system (AGILENT , Germany) coupled to Agilent 6530 Quadrupole T ime of Flight (AGILENT , Singapore). Mass spectrometry (MS) is an incredibly diverse and constantly evolving technology, implemented in labs across the globe to solve almost any analytical problem.

In 1996, Waters invention of QTof technology represented a huge leap forward in how samples are analyzed in the laboratory and in the amount of information available to scientists from a single MS/MS analysis. LC-QTOF-MS Analysis.
