Impressive Performance for small Sr loads on Phoenix TIMS

Posted on 28th February, 2012

Phoenix has been recognized as the most sensitive TIMS currently available. In order to characterize the system we analyzed small loads of NBS 987 to test Sr ionization efficiency and provide an insight into typical system performance. Using a modified loading technique with a tantalum activator on a rhenium center filament, very high atom to ion...

TIMS produces absolute isotope ratio values rather than values normalized to a standard as is usual in gas IRMS. There is however always a small difference from machine to machine which explains why although modern TIMS systems can achieve a measurement precision of  less than 5ppm, accuracy specifications are usually of the order of 25 or 30 ppm. Nevertheless we would expect instruments made in the same factory within a few...

New Application Note: 87Sr/86Sr of sub 10ng loads of NBS987

Posted on 27th September, 2011

Sub-millimeter variations in Sr isotope ratios across zoned minerals and in fluid inclusions continue to be of interest to geologists. Whilst the use of ion microprobe systems provide the best spatial resolution, TIMS coupled with micro-milling devices provide the best accuracy and precision.  Sample sizes are small – perhaps only a nanograms of Sr –...
