Inductively Coupled Plasma Mass Spectrometer (ICP-MS)

Laser Ablation ICP-MS

The laser ablation ICP-MS system is used for micro-sampling of solid material for trace element, predominantly cation analysis. It consists of a 213nm Nd:YAG New Wave pulsed solid state laser (NWR213 New Wave) 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. Advances in LAICPMS now include mapping samples for trace elements and their isotopes using a new 193nm RESOlution LR Excimer Laser coupled to an Agilent 7900 ICP-MS.

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. Routine elemental analysis of minerals and fish otoliths are carried out on the New Wave NWR213 laser system attached to our Agilent 7900x ICP-MS Open external site link in new window.

Agilent 7900x with attached RESOlution LR 193nm Excimer laser system

In late 2011, Adelaide Microscopy took delivery of a RESOlution LR Open external site link in new window 193nm Excimer laser system and new Agilent 7900x Open external site link in new window ICP-MS. The prime directive of this acquisition was to further enhance the low level concentration elemental mapping capabilities of Adelaide Microscopy. The large format S155 sample chamber designed by Laurin Technic Pty which offers improved sample throughput, and excellent signal sensitivity, washout, and stability.
