Effect of resolution on the shape of mass spectra of proteins: Some theoretical considerations

A small computer program has been written to investigate the effect of increasing the mass resolution to very high values (106) on the shape of mass spectral peaks of small to medium‐sized proteins. Previous work in this area has generally limited discussion to mass resolutions of a few thousand. Now that mass spectra of proteins are obtainable with a mass resolution exceeding one million, it is important to be able to conveniently generate theoretical spectra at the same resolution.
