Abstract

Laser induced breakdown spectroscopy (LIBS) is used for the identification of elements in any material or substance. Samples of four different tea brands contained many elements, some are natural tea elements while some adulteration has been added. These four tea brands are local tea and three brands have been analyzed by LIBS. Some impurities have been identified in these samples. Plasma parameters like plasma temperature and electron number density have been calculated and checked the variation in these samples. This can easily be used as a helpful analytical tool for quality and safety control.

茶叶中化学元素的鉴定和使用激光诱导击穿光谱法（LIBS）的血浆参数计算

摘要

激光诱导击穿光谱法（LIBS）用于鉴定任何材料或物质中的元素。四个不同茶品牌的样本包含许多元素，一些是天然茶元素，同时添加了一些掺假。这四个茶品牌是当地茶，LIBS对三个品牌进行了分析。在这些样品中已经鉴定出一些杂质。已计算出血浆参数，如血浆温度和电子数密度，并检查了这些样品的变化。这可以轻松用作质量和安全控制的有用分析工具。
