Time-resolved electrospray mass spectrometry — a brief history

Abstract: This review describes the evolution of time-resolved electrospray ionization mass spectrometry (TRESI-MS), a technology that was developed in large part at Western University. TRESI-MS was initially designed to characterize rapid chemical and biochemical reactions occurring on the millisecond time scale without need for a chromophore. Early TRESI-MS setups usually consisted of continuous-flow rapid mixers with a fixed tee for analysis of a single time point, and later adjustable reaction chamber devices allowi… Show more

“…To further examine the structural and dynamic changes associated with RNA binding to hLa, we used HDX-MS (38,39). This approach provides more structural detail than CIU and specifically measures the impact of ligand binding in solution.…”

“…[14][15][16][17] The most common application of these systems can be found in time-resolved mass spectro-metry, an analytical method used for the study of chemical kinetics or biological dynamics. 18,19 A typical laminar flow setup for continuous-flow experiments consists of two capillaries through which the reactants are pumped to a T-mixer, which is again connected to the capillary in which the reaction takes place. In this paper, we present such a microfluidic setup for the determination of kinetic association rate constants of radiopharmaceuticals.…”

“…However, it is often difficult to obtain detailed molecular mechanistic information under normal operating conditions because intermediates have short lifetimes (typically less than~1 s), exist in a complex and dynamic matrix involving multiple reaction pathways, and have low concentrations [2][3][4][5]. These difficulties are significantly more pronounced for homogenous multi-catalytic systems [6], which show great promise for rapidly achieving onepot complex transformations that improve efficiency, selectivity, and enantiomeric purity.…”
