Several researchers have stressed that support tools should be added to game environments to ensure that learning takes place. In this paper we will
Interpreting Electrospray Mass Spectra
This site is a tutorial on interpretation of electrospray mass spectra of multiply charged molecules. It provides a simple explanation of the electrospray process and the potential for the creation of multiply charged species, especially when working with peptides.
