Ever since the introduction of laser technology to the field of mass spectrometry, several disciplines evolved providing solutions to challenging scientific and analytical tasks in research and industry. Among these are techniques involving multiphoton ionization such as Resonance‐Enhanced Multiphoton Ionization (REMPI, R2PI) and Mass‐Analyzed Threshold Ionization (MATI) spectroscopy, a variant of Zero Kinetic Energy (ZEKE) spectroscopy, that possess the ability to selectively ionize certain preselected compounds out of complex mixtures, for example, environmental matrices, with a high level of efficiency. Another key feature of multiphoton ionization techniques is the ability to control the degree of fragmentation, whereas soft ionization is most highly appreciated in most applications. In cases where rich fragmentation patterns are desired for diagnostic purposes, Photodissociation mass spectrometry (PD‐MS) is applied successfully. PD‐MS allows for the cleavage of selected chemical bonds. With the introduction of chromophoric labels in PD‐MS, it became possible to target certain molecules or groups within a molecule. In this review article, an overview of the basic principles and experimental requirements of REMPI and MATI spectroscopy and PD mass spectrometry are given. By means of selected examples, the latest developments and application possibilities in this field over the past decade with special focus on the German research landscape are pointed out. © 2018 Wiley Periodicals, Inc.

可见光和紫外激光在质谱中的光电离和光碎裂

自从将激光技术引入质谱领域以来,几门学科不断发展,为解决研究和工业领域中具有挑战性的科学和分析任务提供了解决方案。其中包括涉及多光子电离的技术,例如共振增强多光子电离(REMPI,R2PI)和质量分析阈值电离(MATI)光谱,零动能(ZEKE)光谱的一种变体,具有选择性地电离某些预选离子的能力。从复杂的混合物(例如环境基质)中分离出高效率的化合物。多光子电离技术的另一个关键特征是能够控制碎片化程度,而在大多数应用中,软电离是最受赞赏的技术。如果出于诊断目的需要丰富的碎片图谱,则可以成功应用光解离质谱(PD-MS)。PD-MS允许裂解选定的化学键。随着PD-MS中发色标记的引入,靶向某些分子或分子中的基团成为可能。在这篇综述文章中,对REMPI和MATI光谱以及PD质谱的基本原理和实验要求进行了概述。通过一些实例,指出了过去十年中该领域的最新发展和应用可能性,特别侧重于德国研究领域。分级为4 +©2018 Wiley Periodicals,Inc.Mass Spec Rev 38:202–217,2019。PD-MS允许裂解选定的化学键。随着PD-MS中发色标记的引入,靶向某些分子或分子中的基团成为可能。在这篇综述文章中,对REMPI和MATI光谱以及PD质谱的基本原理和实验要求进行了概述。通过一些实例,指出了过去十年中该领域的最新发展和应用可能性,特别侧重于德国研究领域。分级为4 +©2018 Wiley Periodicals,Inc.Mass Spec Rev 38:202–217,2019。PD-MS允许裂解选定的化学键。随着PD-MS中发色标记的引入,靶向某些分子或分子中的基团成为可能。在这篇综述文章中,对REMPI和MATI光谱以及PD质谱的基本原理和实验要求进行了概述。通过一些实例,指出了过去十年中该领域的最新发展和应用可能性,特别侧重于德国研究领域。分级为4 +©2018 Wiley Periodicals,Inc.Mass Spec Rev 38:202–217,2019。概述了REMPI和MATI光谱以及PD质谱的基本原理和实验要求。通过一些实例,指出了过去十年中该领域的最新发展和应用可能性,特别侧重于德国研究领域。分级为4 +©2018 Wiley Periodicals,Inc.Mass Spec Rev 38:202–217,2019。概述了REMPI和MATI光谱以及PD质谱的基本原理和实验要求。通过一些实例,指出了过去十年中该领域的最新发展和应用可能性,特别侧重于德国研究领域。分级为4 +©2018 Wiley Periodicals,Inc.Mass Spec Rev 38:202–217,2019。
