Fig. 1From: JS-MS: a cross-platform, modular javascript viewer for mass spectrometry signalsIn a mass spectrometry experiment (a), each unique molecule in a sample will create a unique 3-d signal group, called an isotopic envelope (indicated by color in (c)), for every charge state found in the analysis. Each isotopic envelope is comprised of several isotope traces (indicated by dashes in (b))Back to article page
