Publikováno v: Journal of Analytical Atomic Spectrometry. 32:2271-2280

Precise isotope ratio measurements in the nuclear field often require hyphenation of separation techniques with multicollector inductively coupled plasma mass spectrometry (MC-ICPMS). Among these separation techniques, electrokinetic methods are very
