Abstract

A comprehensive understanding of chemical composition of cultural heritage materials usually requires several complementary analytical techniques. Given the fragility and value of artworks, minimizing or avoiding sampling and performing in situ analysis under ambient light is an important goal. This article outlines a novel prototype designed to merge LIBS, laser-induced fluorescence spectroscopy (LIF), Raman spectroscopy using a single pulsed laser, and reflectance spectroscopy in a multi-spectroscopic characterization system for cultural heritage analysis (SYSPECTRAL). The aim is to analyze cultural heritage materials in their original place, obtaining both elemental and molecular information at such same point that is not always insured with several separated experimental settings. The SYSPECTRAL system focuses on compactness, mobility, and ease of operation. Software designed for the prototype controls multi-spectroscopic measurements, allows for image capture, precise localization, and data acquisition. Reflectance spectra examined the material and colors at the surface, and the LIBS-LIF-Raman package examines the stratigraphic structure of a multi-layered painted sample.

用于文化遗产材料分析的多光谱表征系统（SYSPECTRAL）：构思与实例。

全面了解文化遗产材料的化学成分通常需要几种互补的分析技术。鉴于艺术品的脆弱性和价值，最大限度地减少或避免取样并在环境光下进行原位分析是一个重要目标。本文概述了一种新型原型，该原型旨在将激光诱导荧光光谱（LIBS）、激光诱导荧光光谱（LIF）、使用单脉冲激光的拉曼光谱和反射光谱合并到一个用于文化遗产分析的多光谱表征系统（SYSPECTRAL）中。该系统的目的是在文化遗产材料的原址对其进行分析，在同一个点上同时获得元素和分子信息，而在多个独立的实验环境下，这些信息并不总能得到保证。SYSPECTRAL 系统的重点是结构紧凑、机动性强和易于操作。专为原型设计的软件可控制多光谱测量，进行图像捕捉、精确定位和数据采集。反射光谱检查了表面的材料和颜色，LIBS-LIF-Raman 软件包检查了多层彩绘样品的地层结构。

期刊介绍： Talanta provides a forum for the publication of original research papers, short communications, and critical reviews in all branches of pure and applied analytical chemistry. Papers are evaluated based on established guidelines, including the fundamental nature of the study, scientific novelty, substantial improvement or advantage over existing technology or methods, and demonstrated analytical applicability. Original research papers on fundamental studies, and on novel sensor and instrumentation developments, are encouraged. Novel or improved applications in areas such as clinical and biological chemistry, environmental analysis, geochemistry, materials science and engineering, and analytical platforms for omics development are welcome. Analytical performance of methods should be determined, including interference and matrix effects, and methods should be validated by comparison with a standard method, or analysis of a certified reference material. Simple spiking recoveries may not be sufficient. The developed method should especially comprise information on selectivity, sensitivity, detection limits, accuracy, and reliability. However, applying official validation or robustness studies to a routine method or technique does not necessarily constitute novelty. Proper statistical treatment of the data should be provided. Relevant literature should be cited, including related publications by the authors, and authors should discuss how their proposed methodology compares with previously reported methods.
