Infrared Spectroscopy and Mass Spectrometry

crab.rutgers.edu

Mass Spectrometry (MS) MS provides information concerning the molecular weight of a molecule (and often other structural information). Very small sample sizes are required (2mg, "if you can see it, you can MS it", but a destructive technique), and high resolution mass spectrometry (HRMS) can determine molecular weight to 3-4 decimal places.

Time-of-Flight Mass Spectrometry - Agilent

www.agilent.com

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-ics, have significantly improved TOF resolution. This improved resolution, combined

• Mass spectrometry involves the interaction of charged species with magnetic and/or electric fields, giving rise to a mass spectrum. The term "mass spectroscopy" is deprecated, for the technique is primarily a form of measurement, though it does ... A high resolution polychromator can be used to produce an emission

2.3 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.
