Abstract
Este trabajo se realizó en el Laboratorio de Óptica y Láseres del Departamento Académico de Física de la Facultad de Ciencias Físicas y Matemáticas de la Universidad Nacional de Trujillo y se desarrolló en el marco del proyecto de investigación PIC N ° 05-2021 Mod. 01 V Convocatoria de Proyectos con financiamiento del Canon Minero de la Dirección de Investigación y Ética de la UNT. El objetivo principal fue usar la técnica de análisis de Espectroscopia de Plasmas Inducidos por Láser (LIBS) para hacer análisis elemental de objetos arqueológicos de metal. Se logró analizar 9 diferentes objetos arqueológicos de metal procedentes de dos sitios arqueológicos de Huanchaco, en la costa norte de Perú, determinándose que todos contenían cobre y algunos también oro y plata; estos resultados coincidían con los obtenidos mediante análisis por fluorescencia de Rayos X, concluyéndose que la técnica LIBS es apropiada para el análisis elemental de objetos arqueológicos metálicos de manera rápida y cualitativa sin preparación de la muestra
Abstract This work was carried out at the Optics and Lasers Laboratory of the Academic Department of Physics of the Faculty of Physical and Mathematical Sciences at the National University of Trujillo and was developed within the framework of the research project PIC No. 05-2021 Mod. 01, V Call for Projects with funding from the Mining Canon of the Research and Ethics Directorate of UNT. The main objective was to use the Laser-Induced Breakdown Spectroscopy (LIBS) analysis technique to perform elemental analysis of archaeological metal objects. Nine different archaeological metal objects from two archaeological sites in Huanchaco, on the northern coast of Peru, it was determined that all of them contained copper, and some also had gold and silver. These results aligned with those obtained through X-ray fluorescence analysis, leading to the conclusion that the LIBS technique is suitable for the rapid and qualitative elemental analysis of archaeological metal objects without sample preparation
