Laser Ablation-Inductively Coupled Plasma-Mass Spectrometry (LA-ICP-MS): An Introduction for Archaeological and Cultural Materials

Dr. Lindsay Bloch, Florida Museum of Natural History & Ben Yahola from the Seminole Nation of Oklahoma

LA-ICP-MS is an analytical technique that uses a microscopically focused laser to analyze materials and obtain their elemental composition. This technique is particularly well suited for small, rare, or fragile objects, but is commonly used for a wide range of materials, including pottery, lithics, bone, and glass. Samples can remain whole or have small fragments removed for analysis. This talk will outline the method of LA-ICP-MS, discuss best practices, and provide several case studies of successful projects.

"The Intersection of Archaeological Science and Tribal Perspectives" speaker series will include presentations regarding the basics of several specialized archaeological science techniques and how those can intersect with tribal perspectives regarding sampling, destructive analysis, consultation, and NAGPRA. Each lecture will conclude with input from various tribal discussants from the Muscogee Nation, Seminole Tribe of Florida, and the Eastern Band of Cherokee Indians. This series is for students and professionals who would like to learn about some of the specialized methods employed in archaeological investigations and how they can be better integrated with tribal interests.
