Carbon-11 or 11 C is a radioactive isotope of mass 11 of the element carbon, which has a half-life of about 20, 5 minutes decays to boron-11. The atomic nucleus of the nuclide is made up of 5 neutrons and the 6 element-specific protons.
This tool allows calculating the theoretical isotopic distribution and monoisotopic mass from a Molecular Formula. It is possible to indicate predefined groups, chemical modification of amino acids, specify a given isotope, and modify the isotopic abundance.
27 maj 2024 · predict the relative heights of the M +·, (M + 1) +·, etc., peaks in the mass spectrum of a compound, given the natural abundance of the isotopes of carbon and the other elements present in the compound.
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.
Are all atoms of an element the same? How can you tell one isotope from another? Use the sim to learn about isotopes and how abundance relates to the average atomic mass of an element.
Simulates the exact isotopic distribution and the mass spectrum of a single or multiple chemical compounds and high molecular mass polymers.
This page allows you to perform three calculations: The mass error of an assignment, when comparing a theoretical m/z and an experimentally observed m/z. The theoretical m/z of the monoisotopic peak for a given molecular formula.
