Web1 jul. 2010 · A time-of-flight (TOF) mass spectrometer is a nonscanning mass analyzer that emits pulses of ions (or transients) from the source. The ions are accelerated so that they have equal kinetic energy before entering a field free drift region, also known as the flight tube. See Figure 2 for a diagram of a TOF-mass spectrometry (MS) system. WebTime-of-flight mass analyzers have significant advantages over quadrupoles for many applications. Simultaneous measurement of all mass-to-charge ratios with time-of-flight mass spectrometry improves speed and sensitivity, ensures that no important information is lost, and makes it easier to identify analytes and interpret measurements. WebTwo basic types of mass spectrometers are commonly used for this purpose; Matrix-assisted laser desorption/ionization (MALDI)-time-of-flight (TOF) mass spectrometry (MS) and electrospray ionization (ESI)-MS. MALDI-TOF instruments are now quite common in biochemistry laboratories and are very simple to use, requiring no special training. de una vez lyrics translated english
