METHOD AND APPARATUS FOR THE CORRECTION OF MASS ERRORS IN TIME-OF-FLIGHT MASS SPECTROMETRY

摘要

A method of correcting mass-spectral data acquired using a time-of-flight mass spectrometer (1) is disclosed comprising recognising in an observed mass spectrum the mass peaks and determining the observed peak area and mass centroid. Then, using a correction table, the observed mass centroid is corrected for the effect of detector dead-time. The correction table is generated using a Monte Carlo simulation.
