The basic mass spectrometer measures an ion's mass-to-charge (m/z ... which features a MALDI (matrix-assisted laser desorption ionization) source and tandem time-of-flight (TOF/TOF) mass analyzers. 1 ...

So-called triple-quad instruments contain two quadrupoles for mass filtering flanking a third that acts as a collision cell. In MS mode, the quadrupole scans across an m/z range, sequentially ...

Recently, mass spectrometry methods have been developed ... The ions separated by TOF are usually detected using an ion conversion dynode and an electron multiplier device. Peeling, R.

Surface-enhanced laser desorption/ionization time-of-flight mass spectrometry (SELDI-TOF-MS) represents the successful combination of retentate chromatography and mass spectrometry, and this ...

8 What makes MALDI-TOF mass spectrometry so useful in biosciences is that many of the species being detected have very high molecular weights and are prone to extensive fragmentation. For viral ...

The Agilent 6220 TOF LC/MS delivers exceptional analytical performance ... identification of impurities in complex matrices faster and with greater confidence than with other methods. Coupled to the ...
