Increasing Speed of UHPLC-MS Analysis Using Single-stage Orbitrap Mass Spectrometer

Instrument Type: LCMS

Productivity of an LC-MS system is measured in samples per day. Modern ultrahigh pressure LC-MS (UHPLC-MS) methods increasingly deal with very short gradients, leading to chromatographic signals with peak widths below 5 seconds at the base. It is still a challenge for high-resolution, accurate mass (HR/AM) systems to provide a sufficient number of scans (=10) across the chromatographic peak in full scan mode without compromising sensitivity and selectivity. We describe a system that addresses these challenges.
