Lithium isotope analysis
WebWe report the origin of isotope fractionation induced by the choice of laser parameters and a method for accurate in situ determination of lithium (δ 7 Li) and boron (δ 11 B) isotope ratios in glasses and minerals using laser ablation multiple Faraday collector inductively coupled plasma mass spectrometry (LA-MFC-ICPMS). WebLi isotope compositions are expressed as δ7LirelativetotheL-SVECstandard( Li/6Li=12.1729;Qietal.,1997),so that the true7Li/6Li for KBH-1 is assumed to be 12.2143. …
