Nuclear Magnetic Resonance (NMR) spectroscopy is a technique used to monitor chemical reactions and determine the structures of chemicals. Because it is such useful technique, it is used in a wide variety of chemistry teaching and research programs. Every chemistry department that is involved in teaching and research has a laboratory devoted to NMR spectroscopy. NMR spectrometers have three main parts: an electronics console, a probe, and a powerful superconducting magnet. Our primary research NMR spectrometer, a Varian UNITY 400, is now almost twenty years old. Due to the age of this instrument, the electronics console suffers from many breakdowns. Often it is difficult to find replacement parts because many of the components of the console are now obsolete. Hence it is becoming increasing difficult to keep this critical instrument running. During the lengthy periods it is out of service, the research programs that rely on this instrument suffer delays.

核磁共振（NMR）光谱是一种用于监测化学反应和确定化学品结构的技术。因为它是如此有用的技术，它被用于各种各样的化学教学和研究计划。每个参与教学和研究的化学系都有一个专门研究NMR光谱的实验室。核磁共振波谱仪有三个主要部分：电子控制台，探头和强大的超导磁体。我们的主要研究NMR光谱仪，Varian UNITY 400，现在已经有近20年的历史了。由于这台仪器的年龄，电子控制台遭受许多故障。通常很难找到替换零件，因为控制台的许多组件现在已经过时了。因此，保持这一关键仪器的运行变得越来越困难。在它长期停止服务期间，依赖该仪器的研究计划受到延误。
