J. Anal. At. Spectrom., 2009, 24, 1517
DOI: 10.1039/b906417f
Direct determination of Ca, Co, Cr, Cu, Fe, Mn, Ni and Ti in boron carbide powders with different particle size distributions by slurry sampling total reflection X-ray fluorescence spectrometry (TXRF) is described.
Measurement of lithium isotope ratios by quadrupole-ICP-MS: application to seawater and natural carbonates
Sambuddha Misra and Philip N. Froelich,
J. Anal. At. Spectrom., 2009, 24, 1524
DOI: 10.1039/b907122a
Oceanic foraminifera are known to carry records of trace elements and isotopes from the ancient seawater in which they grew. We developed an improved method for high precision lithium isotope ratio determination from mass-limited foram shells.

Technical Notes
Comparison of interface cones for analysis of sodium-rich samples using quadrupole ICP-MS
