Figure 2. Schematic diagrams of the standard mass analyzer configuration used in metabolomic investigations.

Figure 2

(A) The schematic diagram of a Sciex TripleTOF quadrupole time of flight mass analyzer (QTOF) is depicted with a quadrupole mass filter capable of 1 Dalton resolution as the first mass analyzer and a time of flight mass analyzer as the second high resolution mass analyzer. (B) The schematic diagram of a Thermo QExactive Orbitrap mass spectrometer is depicted with a quadrupole mass filter capable of 0.4 Dalton mass resolution as the first mass analyzer and an Orbitrap as the second high resolution mass analyzer. Both types of mass analyzers are commonly employed in metabolomic research.
