Technical note on Phoenix’s new Xact Faraday amplifiers

Posted on 22nd May, 2012

    Isotopic precision, especially on small samples, relies on an optimal signal to noise ratio in the collector system. Hence it is crucial that Faraday amplifier noise is at an extremely low level and is stable across a range of integration periods. The Johnson law describes the theoretical noise...

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...

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...
