Cl/S isobar separation using an on-line reaction cell for 36Cl measurement at low energies

A radio-frequency quadrupole ion guided reaction cell, incorporated into a system for generating, decelerating and accelerating anions for analysis by accelerator mass spectrometry is described. Tests of this system for the suppression of the unwanted isobar 36S in the analysis of 36Cl and the measurement of a standard 36Cl reference material are reported.
