Potential for 90Sr measurement on the Phoenix TIMS

Posted on 9th October, 2012

90Sr is a fission product of uranium and plutonium and is expected to be released in a high quantity in a nuclear accident. Sr easily substitutes for Ca and accumulates in bone hence exposure to radioactive Sr represents a significant cancer risk. Additionally, the relatively long half life of 90Sr...

Multiple ion counting application note added to the downloads page (T10412)

Posted on 30th April, 2012

TIMS analysis of very small (picogram) sample loads results in ion signals that are small and short lived. Whilst the ion-counting Daly can be used in peak jumping mode for such samples, the constantly varying signal intensity really calls for a multi-collector approach and in these circumstances multiple ion-counting becomes the...

New Application Note – Total evaporation (TE) of 500ng U500 using Phoenix TIMS

Posted on 16th September, 2011

High sensitivity measurements of U are of crucial importance in a number of fields. Whilst atom/ion efficiency of >1% has been achieved for point source methods using carbon, for analyses of larger U loads (~500 ng) using a standard filament assembly with no carbon the typical atom/ion efficiency is in the range 0.005% to 0.01%. To test the ionization efficiency and precision achievable...
