✦ Synopsis

The smtablhty of a recently published extraction chromatographlc method to Isolate strontmm from geologIca samples for lsotoplc analyses by thermal romzatlon mass spectrometry was evaluated This method has several slgmficant advantages over conventlonal Ion-exchange techniques high selectlvlty combined Hrlth high recoveries, overall slmphc~ty and the use of very small reagent volumes of a smgle acid (HNO,) Satisfactory blank levels were obtained on new columns, but memory effects could not be totally eliminated from already used extraction chromatographlc matenal Determmatlons of "Sr/ 8%r ratios and Sr concentration by Isotope ddutlon followmg the proposed method are reported for thirteen mternatlonal rock standards
