This application generates high-resolution color-coded isotope patterns at a selected resolution. It is designed for small molecules <= 1000 daltons. Elemental formulas are limited to ten common elements (C, H, Br, Cl, F, I, N, O, P, or S).  This application allows the user to observe how different resolution settings and molecular formulas will affect the observed isotope patterns.  Individual isotopes are color-coded; the user can easily observe the contribution of each isotope to the overall result.
