High Precision 3ppm (2RSD) Strontium isotope ratio data produced during instrument test

Posted on 16th May, 2017

Introduction The information below shows the most recent factory test data on replicate measurements of 150ng Sr NBS987 demonstrating the exceptionally high precision 87Sr/86Sr reproducibility that can be achieved on the Phoenix TIMS during regular multidynamic analysis. Normal sample loading techniques were utilised; 1µl of TaF solution was initially dried...
