The Duetta was used to collect Excitation-Emission Matrices that distinguish different species of essential oils, as well as the same species by region of origin. A 50/50 mixture of lavender and eucalyptus demonstrated the ability of the approach to qualitatively identify an adulterant.

Verifying the quality of lavender essential oil is crucial to ensure it is safe for its intended use, and to ensure consumers aren’t being deceived into buying inferior products. Two samples of lavender essential oil with identical label claims of "Pure", one from a supplier that tests for quality and one that does not, were evaluated with A-TEEM spectroscopy and GC-MS.

滑石是一种天然矿物，具有从白色到各种深浅不一的灰色和绿色。一些滑石呈红色至棕色，通常是其中含有杂质的结果。滑石有着广泛的应用；它可用于纸张（作为填料）、面粉和滑石粉、肥皂、防火屋顶、润滑剂、电绝缘材料和陶器制造。

Mineral-based sunscreens have gained popularity due to their excellent ability to scatter ultraviolet (UV) rays without causing photo-induced skin irritation from chemical-based sunscreens. Of the 18 U.S. Food and Drug Administration approved active ingredients for sunscreen drug products, only two are mineral based. Zinc oxide remains stable at high temperature and in neutral pH, covers a broad spectrum of UV radiation, and is even mildly antibacterial. Three over-the-counter zine oxide sunscreens were purchased and analyzed using Partica LA-960V2 Laser Diffraction Particle Size Analyzer. A standard 15 mL fraction cell accessory fitted with a magnetic stir bar was chosen for this experiment.

在配方过程的最后一步，制药和化妆品行业必须控制他们的产品，检查化合物在最终产品中的分布，或其应用形式，即分散在皮肤上的皮内产品，是否均匀和稳定，以保证产品的功效。在本文中，我们介绍了为什么共焦拉曼光谱仪是表征药物和化妆品的适宜工具。

氧化铁是磁性材料。甲基硅油处理为颗粒增加了一定程度的润滑性，尽管它们仍然具有磁性，但可以实现更好的颜色饱和度。

本应用文档概述了三种不同的光谱工具用于表征防晒霜的相关特性，并讨论获得的相关结果。包括用于光活性研究的荧光光谱技术，用于成分研究的粒径分析以及用于配方研究的拉曼表征。

许多化妆品中含有颗粒材料或乳液。这些组分的粒度分布影响着最终产品外观与稳定性。

共聚焦拉曼光谱是各个领域的重要分析工具，它在化妆品和/或制药领域的具体应用中显示出很高的效率。它的非侵入性和高分子灵敏度使其成为表征皮肤和化妆品等材料的首选分析技术之一。

本研究利用 PSA300 自动图像分析系统来量化各种软膏和乳膏的大小和形状。

生物组织含有吸收光的发色团，以及吸收和再发射光的荧光团(荧光效应)。光的吸收取决于发色团的含量及其在有机物中的分布。

本征蛋白荧光团的荧光光谱已被广泛研究并应用于生物领域。

开发和评价UVA (320-400 nm)防晒霜非常重要，因为UVA阳光可以深入人体皮肤，造成严重的内部损伤，以及红斑和光老化

共焦拉曼光谱开始被认为是在体内条件下对生物组织和人类皮肤进行非侵入性研究的一种高潜力技术。拉曼光谱可用于获得有关皮肤分子组成的信息，其范围可达皮肤表面以下几百微米。
