Laser Ablation: ESI Lasers NWR193 and UP213

Laser ablation permits micro-scale spatial analyses. Samples of almost any type can be positioned inside a chamber where a laser beam (typically 2-150μm wide) is focussed onto the sample surface causing material to be ablated, which is then transported to any of our ICP-MS instruments. This permits spatially resolved high sensitivity elemental and isotopic analysis. There are diverse applications in geology, materials science, biology, medicine and forensics.

We have two systems for ESI Lasers, an NWR 193 (excimer) and a UP213 (Nd-YAG). The systems are self-contained and mobile, allowing them to be coupled to any of our ICP-MS instruments.

Current activity

Examples of some of the work being carried out using these systems include:

Consultancy Work

In addition to carrying out analyses to support research projects across Southampton University and through collaborations around the world, we also undertake bespoke analyses on behalf of commercial partners. We have a group of expert scientific and technical staff who are happy to engage in confidential discussions and provide quotes for interested users.

Future Work

We work closely with groups within NOCS, across Southampton University and from research organisations worldwide. We are always looking to extend our research portfolio and welcome enquiries from potential collaborators, especially those seeking support for post-doctoral fellowships.
