Abstract

Facile generation of series of singly charged radical anions (S_n^-•; n = 1-15) and cations (S_n^+•; n = 2-11) by direct laser ionization renders elemental sulfur an excellent material for the low-mass-region calibration of time of flight (TOF) mass spectrometers. Upon irradiation by a 337-nm UV laser, elemental sulfur undergoes facile ionization without the need of an additional laser-absorbing matrix. An intense and evenly spaced set of peaks is obtained in both modes.
