Resolution Ladder for High-Resolution Mass Spectrometry [PDF]

Analytical Chemistry, 2017
High-resolution mass spectrometry has become a key technology in life sciences. Since it is often unfeasible to find pairs of analytes with an appropriate mass difference to actually quantify the resolution experimentally, resolution is usually calculated from the shape of a single mass peak.
