Arriving at the University of Virginia in the autumn of 1969, Donald Hunt began his 50+ year career in academics with the study of organometallic chemistry, on which he had done his PhD thesis work, and mass spectrometry, to which he was introduced while a postdoc in Klaus Biemann's laboratory at the Massachusetts Institute of Technology. In the 1970s, Hunt's lab pioneered the use of negative chemical ionization (CI) to enhance sensitivity for studying organic molecules, developed a system for simultaneously obtaining positive and negative CI spectra to augment structure elucidation, and built a prototype triple quadrupole instrument so effective at collisional dissociation that its commercial counterpart became the analytical instrument of choice for mixture analysis for the next decade and beyond. Foreseeing that the future lay in the analysis of biological molecules, by the end of the decade Hunt shifted his focus to peptides. The analysis of protein fragments had suddenly become more accessible thanks to the advent of the triple quadrupole and Barber's introduction of fast atom bombardment. As the 1980s began and Hunt and his team sought to pursue larger and larger pieces of proteins, his attention turned to the development of mass spectrometers with greater mass range. While recounting their memories of these events, several of Hunt's students and colleagues pay tribute to his support for them as individuals, as well as to his infectious enthusiasm for scientific endeavors that he so generously shared.
1969年秋,唐纳德·亨特来到弗吉尼亚大学,开启了他长达50多年的学术生涯,研究他在博士论文中涉及的有机金属化学,以及他在麻省理工学院克劳斯·比曼实验室做博士后时接触到的质谱学。20世纪70年代,亨特的实验室率先使用负化学电离(CI)来提高研究有机分子的灵敏度,开发了一种同时获取正、负CI光谱以增强结构解析的系统,并制造了一台原型三重四极杆仪器,其在碰撞解离方面非常有效,以至于其商业版本在接下来的十年及以后成为混合物分析的首选分析仪器。预见到未来在于生物分子的分析,到20世纪70年代末,亨特将研究重点转向了肽。由于三重四极杆的出现以及巴伯引入快速原子轰击,蛋白质片段的分析突然变得更容易进行。20世纪80年代初,亨特和他的团队试图研究越来越大的蛋白质片段,他的注意力转向了开发具有更大质量范围的质谱仪。在回忆这些往事时,亨特的几位学生和同事称赞他不仅作为个人给予他们支持,还称赞他对科学事业具有感染力的热情,并如此慷慨地与大家分享。
