Time-resolved mass spectrometry (TRMS) is a strategy in analytical chemistry that uses mass spectrometry platform to collect data with temporal resolution.[1][2][3] Implementation of TRMS builds on the ability of mass spectrometers to process ions within sub-second duty cycles. It often requires the use of customized experimental setups. However, they can normally incorporate commercial mass spectrometers. As a concept in analytical chemistry, TRMS encompasses instrumental developments (e.g. interfaces, ion sources, mass analyzers), methodological developments, and applications.
Applications[]
An early application of TRMS was in the observation of flash photolysis process.[4] It took advantage of a time-of-flight mass analyzer.[5] TRMS currently finds applications in the monitoring of organic reactions,[6] formation of reactive intermediates,[7] enzyme-catalyzed reactions,[8] convection,[9] protein folding,[10] extraction,[11] and other chemical and physical processes.
Temporal resolution[]
TRMS is typically implemented to monitor processes that occur on second to millisecond time scale. However, there exist reports from studies in which sub-millisecond resolutions were achieved.[4][5][6]
