Mass Spec ToolsTM

Mass Series Calculator

The Mass Series Calculator lets you calculate the mass-to-charge ratios for compounds that have repeating units and/or multiple charges.

Quickly and easily calculate the mass-charge ratio for:
  • Polymers
  • Cluster ions
  • Multiply charged species such as biomolecules
  • Dimer and multimers
Print the results or save them to a text file, or cut-and-paste for use in other applications.
