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. 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 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.

Narrow: ~1.3 Da. Use for building or searching MS/MS spectral libraries, to improve quality of unidentified MS/MS spectra, and to increase the score of identified compounds. Disadvantage is lower signal. iv. Medium: ~4 Da. Good for general MS/MS work. Higher signal, risk of chimeric spectra. v. Wide: ~9 Da. Not advised for general use. vi.
