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. A method for simultaneous determination of flumequine (FLM), oxolinic acid (OXO), sarafloxacin (SAR), danofloxacin (DAN), enrofloxacin (ENR), and ciprofloxacin (CIP) in tilapia (Orechromis niloticus) fillets, using liquid chromatography-tandem mass spectrometry (LC-ESI-MS-MS QToF) is presented.

In ICP-MS, the TOF mass analyzer excels over sequential mass analyzers when large numbers of isotopes must be measured over an extremely short time span. Such short signals are produced, for example, by single-particles (micro-droplets or nanoparticles) or by fast (low-dispersion) laser ablation cells which enable fast multi-elemental imaging.

2017-11-22 2020-04-10 The Q-TOF MS uses a quadrupole (four parallel rods arranged in a square formation), a collision cell, and a time of flight unit to produce spectra. Lighter ions accelerate faster down the flight tube to the detector, thus determining the ions’ mass-to-charge ratios. Q-TOF MS systems have MS-MS capabilities, and can be coupled to GC or LC systems. Waters Quadrupole Time-of-flight MS systems, featuring QuanTof, Fast DDA and MS E technologies, provide the highest UPLC-MS/MS performance to meet the needs of challenging qualitative and quantitative applications.

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.

Mass spectrometry (MS) is an incredibly diverse and constantly evolving technology, implemented in labs across the globe to solve almost any analytical problem. Our high-quality, intuitive mass spectrometers empower all fields of research and development, setting new standards in performance. Data represents the UPLC-QTOF/MS base peak frequency characteristics of the positive ionization of different saponins, flavonoid compounds, terpenoids, alkaloids, and glycosides obtained from the methanol extract of IM whole plant comparing with the Waters UNIFI library in the positive ionization mode (Figs. 1 and and2).

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. liberates you from routine MS technical tasks The application of LC-MS-QTOF-MS enabled the identification of 46 phytochemicals in baobab fruit pulp. Hydroxycinnamic acids derivatives, hydroxybenzoic acid derivatives, flavonols, and flavan-3-ols (monomeric and polymeric proanthocyanidins), triterpenoid and steroid glycosides saponins were identified in baobab fruit extract.
