随着拉曼光谱议的不断发展,尤其是便携式拉曼光谱仪的普及,与其配套的各种拉曼数据库的建立是十分重要的。目前大多数实验室都依赖进口仪器及其相应的数据库。因此建立我国自己的拉曼数据库具有重要的意义。本文采用目前最先进的数据库软件平台,构建了大型拉曼光谱数据库。本数据库包括宝玉石及其填充物、原生矿物、毒品,农药,打印复印墨迹、化学药剂等数个子数据库,总计有数千条图谱及数据信息。可以通过中文名称、英文名称、化学式、特征峰等多种方式进行查询。系统具有智能化的信息查询模块,并且支持模糊查询。根据最强的三个特征峰值进行搜索,是其区别其他数据库的显著特点。在特征峰搜索模式中,通过依次输入拉曼图谱中的最强特征峰值,经过几次比对和确认可以显示出满足搜索条件的图谱,最终逼近真实结果。操作人员只需经过简单的培训,使用较低硬件配置的计算机,就能够在几秒钟内根据实际测得拉曼图谱,从数据库中查找出与其匹配的信息,从而快速准确的鉴定出其构成与或所属矿物。本数据库在功能上可以不断扩展,包含的数据信息可以不断扩充。该数据库可广泛应用于公安法学,宝玉石真伪,化学分析等各种物相鉴定领域。
With the development of Raman spectroscopy, especially the popularity of portable Raman spectroscopy, it is very important to set up various Raman databases. At present, most laboratories rely on imported instruments and their corresponding databases. Therefore, the establishment of our own Raman database is of great significance. This article uses the most advanced database software platform, build a large-scale Raman spectroscopy database. This database includes several sub-databases of gemstones and their fillers, primary minerals, drugs, pesticides, printing ink and chemicals, and a total of several thousand atlas and data information. You can search by Chinese name, English name, chemical formula, characteristic peak and many other ways. The system has intelligent information inquiry module, and supports fuzzy inquiry. Searching according to the strongest three characteristic peaks is the distinguishing feature of distinguishing other databases. In the characteristic peak search mode, by entering the strongest characteristic peak in the Raman spectrum in sequence, after several alignments and confirmations, the spectrum satisfying the search condition can be displayed, and finally the real result is approached. With simple training and a computer with a low hardware configuration, operators can quickly and accurately identify their composition based on the actual Raman spectra measured in a few seconds from the database by matching their information And or belonging to the mineral. The database can be continuously expanded in functionality, including data information can be continuously expanded. The database can be widely used in public security law, authentic jade jewelry, chemical analysis and other identification phase.
