摘要：

Thirteen collision/reaction gases (CH4, O-2, H-2, CH3F, C2H6, N2O, NH3, SF6, Xe, Ne, N-2, CO and Ar) were investigated to reduce the ArAr+, Ar2H+, Ar2H2+, SeH+, BrH+ and ArCl+ overlaps on Se+ isotopes. N-2 and Ar had particular advantages for the measurement of multiple Se isotopes compared to the other gases. Experiments using CH4 and CD4 determined that H-atom transfer from CH4 to Se+ resulted in the formation of SeH+. (C) 2014 Elsevier B.V. All rights reserved.
