Abstract
An improved procedure for precise measurement of chlorine isotope rati os in geological samples based on Cs2Cl+ ion by thermal ionization mas s spectrometry is reported. Using this procedure the Cl-37/Cl-35 ratio of NIST SRM 975 is determined to be 0.318929 +/- 0.000028(1 sigma) wi th a precision of 0.009%(1 sigma). The procedure has been successfully applied to study the variation of chlorine isotopic compositions in s eawater and to determine atomic weight of chlorine.
