本文介绍了重离子解吸质谱计的基本原理和结构,它是用~(252)Cf或加速器产生的快速重离子轰击样品使分子解吸成离子,然后用飞行时间分析法获得质谱。这种仪器特别适用于生物大分子的研究,文中给出了一些应用实例。
This paper introduces the basic principle and structure of a heavy ion desorption mass spectrometer. It uses a fast heavy ion bombardment sample produced by ~ (252) Cf or an accelerator to desorb molecules into ions and obtain mass spectra by time of flight analysis. This kind of instrument is especially suitable for the research of biological macromolecules. Some application examples are given in this article.
