Novel Portable Laser Ablation Micro-Sampling in Cultural Heritage

This paper describes the evaluation of a prototype semi-portable UV laser ablation (LA) sampling device for provenance and composition studies of transparent and translucent materials such as clear glass, porcelain, feldspar minerals, teeth, etc. encountered in cultural heritage and forensics. Preliminary geochemical analysis (major/trace elements and strontium/lead isotope composition) of two NIST glasses (SRM 610 and 614) and two Corning glasses (A and leaded D) was carried out to validate the system and assess the reproducibility and precision of the data. head with the open ablation cell), a diaphragm micro-pump attached to a single filter holder, and a CMOS color camera. The combined power supply and chiller are not shown.
