The process of Nuclear Magnetic Resonance (NMR) is helping Auburn University unlock the mysteries of polymeric materials. In this article Assistant Professor Bryan Beckingham explains how.
The Importance of Polymers
聚合物材料无处不在，欧洲杯足球竞彩在各种各样的行业和应用中充当关键组件 - 从医疗保健（包括药物输送，植入物材料和抗细菌涂料）到能量系统（例如有机光伏，燃料电池和电池）。
To explore the relationships between polymerization chemistry, polymer architecture, and the resulting material properties, the Beckingham polymer lab carries out fundamental and applied research. Such research is crucial in advancing the thoughtful design of polymeric materials for targeted applications, because knowledge of such fundamental structure property relationships is essential.
Beckingham Lab通常将独特的小分子合成作为聚合物构建块和独特的聚合物进行研究。NMR光谱学是这里的重要工具，因为这些小分子前体和合成聚合物需要精确的分子和大分子表征。
关于Auburn University’s Chemistry Department
奥本大学主要是一所土地，太空和海洋学赠款公共R1研究大学，其化学工程系有100多名研究生和22名教职员工，还有10名博士后研究员和几位来访的教职员工。
Enjoying state-of-the-art facilities, the department is well supported by extramural research grants from a number of federal agencies and industrial companies. Thus, Auburn University can provide opportunities for world-class research at every level. Typically, this department invests $6 - 6.5 million per year on research, making it one of the top 25 departments in terms of research expenditures per faculty member. Moreover, both faculty and graduate students routinely publish papers in premier journals and participate in national and international conferences.
Introducing Pulsar Benchtop NMR analysis
奥本大学（Auburn University）获得了牛津仪器的脉冲星，以促进对这些分子的快速，准确分析，并对聚合和聚合物修饰反应进行动力学跟踪。
Saving valuable time, the Pulsar allows for speedy and accurate feedback on reaction conversion for many of the lab’s syntheses. In addition, for a number of systems, Pulsar provides complete, end-to-end macromolecular analysis without the need to obtain data from a higher field spectrometer. Before the arrival of the Pulsar, this analysis would have been performed at a user facility located in the AU Chemistry department, and with an hourly user charge.
Easy Analysis at your Fingertips
PULSAR的主要优点是其位置，准确性和易用性。在实验室中让PULSAR提供所需的表征信息，而无需安排时间和跨校园旅行到用户设施。相比之下，该大学的本地NMR设施距离实验室只有15分钟的步行路程。此外，使用该设施的大量研究人员和化学实验室，尽快获得所需结果可能是一个挑战。
这就是为什么实验室中脉冲星的存在促进了即时常规分析的原因。例如，验证几个小分子合成的100％转化率的最佳方法是NMR。不必等待访问的优点可以快速决策获得所需产品是否需要更多的时间或其他试剂。表征正在合成的聚合物也是如此。使用PULSAR，很容易分析成功率，或者是否需要毫不延迟重新重新重新制定聚合物。
Fast and User-Friendly
由于获得了快速获取和获得高质量的光谱，脉冲星已成为首选且经常使用的仪器。更重要的是，数据获取的易用性使得在没有研究生的监督的情况下独立使用Pulsar的本科生培训，这有时会伴随在用户设施的付费时间。结果，许多系统都是值得出版的，并且已在区域和民族会议上介绍。最近，该部门在RSC分析师中发表了一份手稿，该手稿验证了低场光谱仪的几种常见聚合物混合物和嵌段共聚物的准确性。这证明了Pulsar提供的值。
Pulsar has been a valuable addition to the university lab of Auburn University, equipping the students and researchers with hands-on, practical experience of NMR.
PULSAR是高分辨率60 MHz台式NMR光谱仪，可提供高质量的1-D和2-D NMR光谱1H，19F，13C和31P. It uses a permanent magnet – thus implying that it requires neither liquid helium nor liquid nitrogen. Advanced, automatic shimming produces a highly homogeneous magnetic field, which makes Pulsar suitable for use in almost any academic or industrial chemistry laboratory.
