  • Laser Ablation ICP-MS laboratory

    This laboratory hosts an NWR-193 HE laser ablation system attached to an Agilent 8900 triple-quadrupole ICP-MS. The instrument was configured to be optimal for the analysis of fluid and melt inclusions in minerals and it also provides outstanding performance for most geochemical applications. The laser ablation system is characterized by excellent visual sample observation, high level of flexibility with beam-size and shape selection (IVA and XYR aperture systems), high attainable laser energy densities on the sample surface to facilitate the controlled ablation of quartz, a two-volume ablation cell and a sophisticated and user-friendly control software. The Agilent 8900 ICP-MS provides very high sensitivities and low backgrounds, and the system is used and maintained in a manner to preserve very low gas blanks and provide excellent limits of detection for most elements. Applications relying on the triple quadrupole design, such as in situ Sr isotope ratio determinations in minerals and glasses are currently being developed. The system shares a room with a Neptune Plus multi-collector ICP-MS, to which the laser ablation system can also be connected. Split-stream application with the simultaneous use of the two mass spectrometers is under development.
