www.ocf.berkeley.edu2.3 Mass Spectrometry The most common mass analyzer paired with MALDI is the time-of-ight (TOF) mass spectrometer. MALDI produces ions in short bursts due to the use of a pulsed laser, and produces a wide variety of ion masses that require a detector with a broad mass range.
Time-of-Flight Mass Spectrometry
www.agilent.comTime-of-Flight Mass Spectrometry Technical Overview Introduction Time-of-flight mass spectrometry (TOF MS) was developed in the late 1940’s, but until the 1990’s its popularity was limited. Recent improvements in TOF technology, including orthogonal acceleration, ion mirrors (reflectron), and high-speed electron-
An Introduction to Gas Chromatography Mass Spectrometry
www.ucl.ac.ukA mass spectrometer is an analytical instrument that produces a beam of gas ions from samples (analytes), sorts the resulting mixture of ions according to their mass-to-charge (m/z) ratios using electrical or magnetic fields, and provides analog or digital output signal (peaks) from which the mass-to charge ratio and the intensity (abundance) of
Fundamental LC-MS Introduction
www.ecs.umass.eduThe mass spectrometer is an instrument designed to separate gas phase ions according to their m/z (mass to charge ratio) value. Mass spectrometry involves the separation of charged species which are produced by a variety of ionisation methods in LC …
