ETV-ICP-MS Analysis of Radium

["Leo M. Lowe" <llowe@senes.ca>]

Hello,



Is anyone familiar with the analysis of radium by electrothermal 

vaporization inductively coupled plasma mass spectrometry (ETV-ICP-MS) (phew) ?



According to a paper by McIntyre et al (1997) in the J. Analytical Atomic 

Spectrometry (Vol.12:547-551) at http://pubs.rsc.org/ej/JA/1997/D9607270.PDF ,

  it has a detection limit of less than 2 fg (femtograms) or about 7 x 

!0(-5) Bq, a very low value.  It is apparently also very quick (minutes) 

compared to analyses based on radioactivity counting techniques.



Is this a practical method for environmental samples? What about the 

costs?  If preferred, feel free to respond directly to me.
