Targeted vs untargeted mass spectrometry
WebJun 18, 2024 · Mass spectrometry-based metabolomics can be broadly divided into two groups: targeted or untargeted (Roberts et al., 2012). Targeted analysis involves multiplexed analysis of a set of defined metabolites, generally using multiple reaction monitoring (MRM) with low-resolution tandem mass spectrometers (Lu et al., 2008). This type of analysis ... WebG. To select the target ion, move the mouse pointer to the target ion and click BOTH mouse buttons at the same time.

Targeted mass spectrometry is a mass spectrometry technique that uses multiple stages of tandem mass spectrometry (MS with n=2 or 3) for ions of specific mass (m/z), at specific time. The values of the m/z and time are defined in an inclusion list which is derived from a previous analysis.
