An efficient, clean procedure for the measurement of element mass fractions in bulk rock nanoparticulate pressed powder pellets (PPPs) by 193 nm laser ablation ICP-MS is presented. Samples were pulverised by wet milling and pelletised with microcrystalline cellulose as a binder, allowing non-cohesive materials such as quartz or ceramics to be processed. The LA-ICP-MS PPP analytical procedure was optimised and evaluated using six different geological reference materials (JP-1, UB-N, BCR-2, GSP-2, OKUM and MUH-1), with rigorous procedural blank quantification employing synthetic quartz. Measurement trueness of the procedure was equivalent to that achieved by solution ICP-MS and LA-ICPMS analysis of glass. The measurement repeatability was as low as 0.5–2% (1s, n = 6) and, accordingly, PPP homogeneity could be demonstrated. Calibration based on the reference glasses NIST SRM 610, NIST SRM 612, BCR- 2G and GSD-1G revealed matrix effects for glass and PPP measurement with NIST SRM 613; using basalt glasses eliminated this problem. Most significantly, trace elements not commonly measured (flux elements Li, B; chalcophile elements As, Sb, Tl, In, Bi) could be quantified. The PPP-LA-ICP-MS method overcomes common problems and limitations in analytical geochemistry and thus represents an efficient and accurate alternative for bulk rock analysis.
