The employment of either doping or standard-sample-bracketing method for mass fractionation during isotope ratio measurement using multicollector-inductively coupled plasma mass spectrometry (MC-ICPMS) assumes that th...
A method for determining Mg/Ca of stalagmite by LA-MC-ICPMS is studied. 24Mg/44Ca (Mass 22, intensity of 44Ca2+ , collected by ion counting and mass 24, intensity of 24Mg+, collected by Faraday cup) ratios were measur...
