  abstract = {{T}he rare earth elements ({REE}s) are valuable tracers in the earth, ocean and environmental sciences. {T}en out of fourteen stable {REE}s have two or more isotopes, making them suitable for quantification by isotope dilution. {W}e present a plasma mass spectrometry based multiple isotope dilution method for high precision {REE} concentration analysis in aqueous media. {K}ey aspects of the method are: (i) flexible spiking of ten {REE}s via two {LREE} and {HREE} mixed spike solutions. (ii) {O}ffline pre-concentration and matrix removal, by ion chromatography for freshwater samples and by iron co-precipitation or ion chromatography with the {N}obias ({TM}) resin for seawater samples. (iii) {H}igh sensitivity detection by sector field-inductively coupled plasma mass spectrometry ({SF}-{ICP}-{MS}). (vi) {T}he use of a desolvation micro-nebulization introduction system to lower polyatomic {B}a and {LREE}-oxide interferences on {HREE}s. {T}he method is suitable for a range of freshwater to seawater type samples, and was validated against {SLRS}-4, {SLRS}-5, and {CASS}-5 reference materials and two {GEOTRACES} marine inter-comparison samples. {L}ong-term external precision on all {REE}s was <2% {RSD}, except {L}a and {C}e. {M}inimum sample volumes are 1 ml for freshwater and 50 ml for seawater. {T}he multispike {SF}-{ICP}-{MS} method should be of particular interest in exploring subtle variations in aqueous {REE} fractionation patterns and anomalies in large numbers of samples.},
