原子吸收光谱wi的知识如何ll contribute to my career growth?

Awareness and need for testing of materials existed even in ancient times and has grown keeping its pace with the growth of human civilization. Today you cannot imagine any man-made product be it a machine tool, glass decorative item, food product, pharmaceutical, plastic ware or for that matter any other product which has not undergone quality control using analytical techniques at some stage of its manufacture. Even our natural resources such as water, air, food grains, fruits and vegetables are certified for human consumption after undergoing laboratory testing.

Analysis of trace metals gained significance on the onset of age of metals. Even in those times it was common knowledge that composition of alloys has a bearing on properties of metals to be used for development of weapons for warfare, hunting, implements, storage of foods and drinking water. Efficacy of herbal medicines based on ancient systems such as Ayurveda, Unani and Siddha is dependent on the presence of trace metals or their oxides in correct amounts. An excess of such components could be disastrous to the consumer.

已经应用了几种分析技术，以检测和定量估计不同类型矩阵中的痕量金属。基于重量法和滴定法的经典技术提供了良好的准确性，但耗时。对高速分析的需求的增加导致引入仪器方法，例如离子选择性电极，UV-VIS光谱技术，原子吸收光谱，ICP - OES - OES和ICP - MS。技术的选择取决于所需的检测水平，可用样品数量和最重要的预算。该主题在文章中在某种程度上涵盖了哪种元素分析技术适合我。

原子吸收光谱is a moderately priced instrumental analysis technique which provides a high degree of accuracy and precision of results. Due to its high analysis throughput it finds its rightful place in university laboratories, pollution control laboratories and industrial quality control laboratories. The present article highlights some areas where an awareness of working of an Atomic Absorption Spectrometer will prove to be an asset in enhancing your professional growth.In case you are engaged in any of the activities or areas discussed in the article or wish to land into such areas you will stand to gain through upgradation of your knowledge and technical skills on this technique.

Mining and Geology

The elemental composition of minerals and rocks provides valuable information on the commercial feasibility of conducting mining activities in areas explored. After mining the ores and minerals need to be tested for composition for efficiency of refining operations. Similarly trace metal analysis is of great value in prospecting for oil and water deposits.

宝石也根据某些痕量金属的存在进行分级。考古文物的元素组成有助于追踪其来源。

Environmental Monitoring

环境监测工业废物，海洋，河流和湖泊的微量金属污染对于建立水的饮酒和商业用途非常重要。重要的是要确定此类样本是否在监管机构设定的安全限制之内。环境监测在设置商业项目的现场评估和可行性中也起着重要作用。

材料开发

Common properties of materials such as hardness, brittleness, grain size, crystalinity and amorphous nature are significantly influenced by composition and trace metals. Trace metal analysis can provide useful information on performance properties of such materials.

Pharmaceuticals

痕量金属分析在配方开发，催化剂效率和剂量极限中起着重要作用。大多数元素具有有益的作用，直到某些规定的限制，但除了这些限制之外，效果是有害的。

食品和饮料

在合成加工食品中，金属拾音器是由于与加工设备和催化转化的接触而进行的。消费者对食品安全的认识正在提高，因此制造商必须确保痕量金属不超过允许的限制，这需要通过原子吸收光谱和其他复杂仪器进行严格的质量控制。

石油和石油

食用油和矿物油都需要在食用前进行精炼。这种精炼操作可以涉及蒸馏和催化精炼。在此类操作过程中，对金属的吸收会导致性能或消费者危害的恶化。机油的痕量金属分析提供了有关发动机零件磨损的有用诊断信息。

农业

土壤的痕量金属构成除了它们的酸性或基本性质，对于确定其生产力和营养价值至关重要。植物的痕量金属成分（叶子，茎和根）就如何在不同的生长条件下分布矿物质给出了一个明显的想法

取证

Trace metal analysis provides valuable information on specimens such as stomach contents for food poisoning, paint chips, fibers and hair strands collected from scene of crime.

随着应用区域的范围进一步扩展，原子吸收光谱的范围实际上是无限的。在如此长的文章中，几乎不可能覆盖所有内容。但是，对该技术的基本了解将使您对此类应用程序有了更深入的了解，并增强您在所选领域的职业前景。
