The in situ non invasive methods have experienced a significant development in the last decade because they meet specific needs of analytical chemistry in the field of cultural heritage where artworks are rarely moved from their locations, sampling is rarely permitted, and analytes are a wide range of inorganic, organic and organometallic substances in complex and precious matrices. MOLAB, a unique collection of integrated mobile instruments, has greatly contributed to demonstrate that it is now possible to obtain satisfactory results in the study of a variety of heritage objects without sampling or moving them to a laboratory. The current chapter describes an account of these results with particular attention to ancient, modern, and contemporary paintings. Several non-invasive methods by portable equipment, including XRF, mid- and near-FTIR, UV-Vis and Raman spectroscopy, as well as XRD, are discussed in detail along with their impact on our understanding of painting materials and execution techniques. Examples of successful applications are given, both for point analyses and hyperspectral imaging approaches. Lines for future perspectives are finally drawn.

使用便携式仪器对绘画进行的非侵入式调查：MOLAB的经验。

在过去的十年中，原位非侵入性方法取得了长足的发展，因为它们满足了文化遗产领域分析化学的特殊需求，在这些文化遗产中，艺术品很少从其所在地转移，很少允许取样，并且分析物种类繁多。复杂和珍贵基质中的无机，有机和有机金属物质。MOLAB是集成移动仪器的独特集合，它极大地证明了现在无需进行采样或将其移至实验室就可以在研究各种遗产时获得令人满意的结果。本章描述了这些结果，特别注意了古代，现代和当代绘画。便携式设备采用的几种非侵入性方法，包括XRF，中红外和近红外 我们将详细讨论UV-Vis和拉曼光谱以及XRD及其对我们对绘画材料和执行技术的理解所产生的影响。给出了用于点分析和高光谱成像方法的成功应用实例。最终为未来的观点画了线。
