In this review various technologies and approaches for the utilization of mass spectrometry in high throughput analyses are discussed. The use of quadrupole-based mass spectrometry in the screening of chemical libraries against enzymatic targets for the identification of inhibitors and/or activators is highlighted. The RapidFire mass spectrometry system, an integrated on-line solid-phase extraction system interfaced to a triple-quadrupole mass spectrometer is described in detail, and the identification of a series of inhibitors of the acetyl-coenzyme A carboxylase (ACC) assay is described.
