Ultra-performance liquid chromatography coupled to quadrupole-orthogonal time-of-flight mass spectrometry.

Abstract

Ultra-performance liquid chromatography (UPLC) utilizes sub-2 microm particles with high linear solvent velocities to effect dramatic increases in resolution, sensitivity and speed of analysis. The reduction in particle size to below 2 microm requires instrumentation that can operate at pressures in the 6000-15,000 psi range. The typical peak widths… (More)
