A brief introduction is presented to the basic principles and application of a quadrupole-time-of-flight (TOF) tandem mass spectrometer. The main features of reflecting TOF instruments with orthogonal injection of ions are discussed. Their operation and performance are compared with those of triple quadrupoles with electrospray ionization and matrix-assisted laser desorption/ionization (MALDI A mass selecting quadrupole and collision quadrupole with time-of-flight device as the second mass selection stage is a hybrid known as a quadrupole time-of-flight mass spectrometer (QTOF MS). [7] [8] Quadrupole-quadrupole-time-of-flight (QqTOF) configurations are also possible and used especially the mass spectrometry of peptides and other 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.
