- MS Online Tools (This Page)
SIS has developed the following online tools/utilities for use by the mass spec community. If you have any suggested improvements/additions we would like to hear from you.
- Isotope Distribution Calculator and Mass Spec Plotter Calculate/plot the isotopic distribution (mass/intensity) from a molecular formula with this online tool. High and low resolution.
- Mass Spectrum Generator Plot a mass spectrum given a list of peak masses and intensities with this online tool.
- Exact Mass Calculator, Single Isotope Version Quickly calculate the exact mass of a single isotope from a molecular formula with this online tool.
- SIS Online GC Chromatogram and Mass Spectrum Viewer Read/view CDF and Agilent .D/data.ms files online.
- Search NIST 14 and Wiley MS Databases Check whether a certain compound or class of compound exists within the NIST 14 or Wiley databases.
- Mass Spec Calibration Compounds and Spectra Mass spectrometer calibration compounds for sale. Also includes spectra.
- Exact Masses of the Elements and Isotopic Abundances Name, symbol, mass and abundance of all isotopes.
Periodic Table with Isotopic Abundances
Click on the element for isotopes of the element.
Here is another periodic table (Lenntech) — includes health and environmental effects (multilingual).
- Mass Spectrometry Software from SIS Charged particle optics simulation with SIMION® 3D. Identify your mass spectra with NIST and Wiley database. Convert your spectra with GC/MS file converters.
