WebIt also offers variable precursor ion isolation width selection from 0.4 Da to full mass range. Orbitrap mass analyzer: The Orbitrap mass analyzer offers unprecedented high resolution accurate mass (HRAM) analysis of ions as a function of their rotational frequencies; these data are converted to mass spectra using fast Fourier transforms (FFTs). WebJan 1, 2024 · Figure 1. In a mass spectrum, resolution (R) can be defined by the width at 50% of the peak height (full width at half maximum: FWHM). Systems with R > 20,000 and mass accuracy < 5 ppm are called high-resolution mass spectrometry (HRMS), in opposition to low-resolution mass spectrometry (LRMS).
