The Campana lab » Microsampling Techniques

Assays for bomb radiocarbon and stable isotope ratios are examples of applications where a particular age or date range in the otolith is required. For these applications the best sampling procedures involve microsampling or coring techniques which physically remove a discrete portion of the otolith.

What is LAICPMS? Applied Spectra

LAICPMS (Laser Ablation Inductively Coupled Plasma Mass Spectrometry) is a powerful analytical technology that enables highly sensitive elemental and isotopic analysis to be performed directly on solid samples. LAICPMS begins with a laser beam focused on the sample surface to generate fine particles – a process known as Laser Ablation.
