| 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. |
