Fourteen samples of tourmaline from the Real Museo Mineralogico of Federico II University (Naples) have been characterized through multi-methodological investigations (EMPA-WDS, SEM-EDS, LA-ICP-MS, and FT-IR spectroscopy). The samples show different size, morphology and color, and are often associated with other minerals. Data on major and minor elements allowed to identify and classify tourmalines as follows: elbaites, tsilaisite, schorl, dravites, uvites and rossmanite. Non-invasive, non-destructive FT-IR and in-situ analyses were carried out on the same samples to validate this chemically-based identification and classification. The results of this research show that a complete characterization of this mineral species, usually time-consuming and expensive, can be successfully achieved through non-destructive FT-IR technique, thus representing a reliable tool for a fast classification extremely useful to plan further analytical strategies, as well as to support gemological appraisals.

通过多方法研究（EMPA-WDS，SEM-EDS，LA-ICP-MS和FT-IR光谱法）对来自费德里科II大学（那不勒斯）真实矿物矿物学中的14个电气石样品进行了表征。样品显示出不同的大小，形态和颜色，并且经常与其他矿物质相关。关于主要元素和次要元素的数据可用于对电气石进行识别和分类，如下所示：硅铝石，硅铝石，鼠尾草，德拉瓦特，uvites和罗斯曼石。对相同样品进行了非侵入性，非破坏性的FT-IR和原位分析，以验证这种基于化学的鉴定和分类。这项研究的结果表明，通过无损FT-IR技术可以成功地完成对这种矿物质的完整表征，通常耗时且昂贵。
