Molecular Formula Calculator

This calculator has been created to assign molecular formulas from high-resolution mass spectrometry of predominately organic samples. As such, only the elements listed below are programmed in. To limit the amount that is displayed, unreasonable guesses with O:C greater than 2, N:C greater than 2, and H:C less than 0.2 are omitted.
