仪器技术对分析化学进步的贡献

Analytical chemistry owes its beginnings to classical analysis techniques.What makes classical analysis techniques popular even todayacknowledges the contribution of classical analysis to advances in analytical method developments. It also emphasizes the fact that to gain a sound hold on advanced analytical instruments you have to have a good grasp over the basics of classical techniques.

今天，分析研究的视野在不可预见的步伐中扩展。增加消费者的要求，安全问题和新材料的发展已经提高了分析科学家在据报道的结果，超低检测限度和分析速度的承诺方面的预期水平。

Industry demands instantaneous results on manufactured products in assembly lines or process streams. Such decisions have far reaching implications on commercial and quality of manufactured goods. These decisions are possible using off-line advanced instrumental analysis techniques as well as online process monitoring. Classical techniques which no doubt provide high accuracy of results are no match when it comes to speed of analysis. Besides the analysis speed automated instrumental methods also ensures freedom from personal bias and errors.What are the benefits offered by modern analytical instrumental methods over non-instrumental methods涵盖长度的一些好处。

Instrumental methods of analysis have exploited several basic properties of matter such as light absorbance, electrical conductivity, viscosity, phase transitions, presence of isotopes, molecular vibrations and selective adsorption of certain species, etc to develop well defined analytical streams such as spectroscopy, chromatography, thermal analysis, electrometric methods and the like. The limitless available options have helped the analytical scientist gain insight into arrangement of atoms and molecules in solids (both crystalline and amorphous), geological specimens and biological samples. Instrumental methods have also significantly contributed to our understanding and development of nano-materials, bio-fuels, semiconductor devices and clinical diagnosis.

微电子，光学和自动化的快速进步进一步促进了仪器技术的进步及其应用范围。然而，它再次强调，分析科学家应该不断升级他或她的分析技能，更新基础知识，并避免成为分析仪器的仅仅是专业技术操作员的陷阱。
