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 Find the mass intensity data of isotopes here. Use our mass spectrometry plotter and isotope calculator to find isotopic distribution of a given chemical formula.- 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 Find the exact mass of isotopes here. Using the chemical formula of a single isotope you can get the exact mass and the relative abundance percentage of that isotope.
SIS Online GC Chromatogram and Mass Spectrum Viewer Read/view CDF and Agilent .D/data.ms files online.
Search NIST 23 MS Databases Check whether a certain compound or class of compound exists within the NIST 23 database.
Mass Spec Calibration Compounds and Spectra Mass spectrometer calibration compounds for sale. Also includes spectra.
Exact Masses of the Elements and Isotopic Abundances Chart of elements, isotopes of elements with exact mass, abundance percentage. Find the abundance of natural isotopes and atomic weights of the elements quickly.
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.
