Time of flight mass spectrometry identifies the elements of a compound by subjecting a sample of ions to a strong electrical field. Illuminating emerging analytical techniques in high-resolution mass spectrometry, Liquid Chromatography Time-of-Flight Mass Spectrometry shows readers how to analyze unknown and emerging contaminants such as antibiotics, steroids, analgesics using advanced mass

time-of-flight (TOF) mass spectrometry, which is a high- resolution mass spectrometry technique that detects drugs on the basis of their exact mass. Using this technique, scanning is performed over all masses for low molecular drugs, and detected signals can be related to a library of exact drug masses. Retention time and fragmentation pattern contribute to the identification. In principle, it The participant will increase knowledge and skills in the use of liquid chromatography/mass spectrometry (QTOF and TOF), develop non-targeted analysis skills, learn new computational approaches, and fine tune scientific writing.
