Abstract
Mass spectrometry MS is widely used in analytical chemistry for such fields as environmental science life science and space science However MS has two fundamental limits the mass peak overlap of ions with the same mass/chargenumber m/z ratio but different charge states m/z overlap and no ability to distinguish different neutral molecules neutral loss We show that these limits can be overcome by using superconducting detectors Superconducting tunnel junctions STJ molecule detectors and superconducting nanostripline detectors SSLDs are suitable for MS because of the choice of fast ns response
