Inductively Coupled Plasma Mass Spectrometers (ICP-MS)
Information on the Agilent 7900x with attached New Wave NWR213 laser ablation system
Adelaide Microscopy houses two Agilent ICP-MS instruments with attached laser ablation systems that are routinely used for fundamental research in geological, ecological, and biological investigation of materials.
The laser ablation ICP-MS system is used for micro-sampling of solid material for trace element analysis. It consists of a 213nm Nd:YAG New Wave pulsed solid state laser (NWR213) coupled to an Agilent 7900x ICP-Quadrupole Mass Spectrometer. Detection limits reach into the ppb range allowing for true trace element analysis of a wide variety of solid material, including geological and biological samples.
Information on the Agilent 7900x with attached RESOlution LR 193nm Excimer laser system
Adelaide Microscopy houses a RESOlution LR 193nm Excimer laser system and Agilent 7900x ICP-MS, used primarily for trace element analyses of solid materials, geochronology of minerals and 2D element mapping. The large format S155 sample chamber designed by Laurin Technic Pty offers improved sample throughput, and excellent signal sensitivity, washout, and stability.

Information on the Solution ICP-MS - Agilent 8900x QQQ-ICP-MS for Solution Analysis
The Solution ICP-MS is used to detect trace levels of metallic cations in bulk solution.
The Agilent 8900x triple quad (QQQ-ICP-MS) is equipped with a collision/reaction cell and mass-shifting capabilities with He, NO2, O2, H2 and NH3 reaction gasses allowing for the removal of matrix interferences common in samples of complex matrices. The extreme sensitivity of the instrument allows theoretical detection limits in the ppt range on samples including, but not limited to, geological, seawater and protein solutions.
