摘要
分析技术的进步对于了解地外有机物的性质、形成和演化历史至关重要。在本章中,我们将简要回顾用于检测和描述地外物质中有机物特征的分析技术。质谱法通常与气相色谱法或液相色谱法结合使用,用于元素和同位素分析,以及识别特定的有机化合物。光谱学涉及分子与不同波长电磁辐射的相互作用。从 X 射线到无线电波,几乎所有波长都可用于光谱测量。最主要的显微和纳米技术是扫描和/或透射电子显微镜。光谱分析和质谱分析也可与显微分析相结合,进行详细的成分研究。
Analytical Techniques for Identification and Characterization of Extraterrestrial Organic Matter
Advances in analytical techniques are essential for understanding the nature, formation, and evolutionary history of extraterrestrial organic matter. In this chapter, we briefly review analytical techniques used to detect and characterize organic matter in extraterrestrial materials. Mass spectrometry is often coupled with gas chromatography or liquid chromatography for elemental and isotopic analysis, and for identifying specific organic compounds. Spectroscopy involves interaction of molecules with electromagnetic radiation at various wavelengths. Almost every wavelength—from X-rays to radio waves—can be used for spectroscopic measurements. The most major microscopic and nanoscopic techniques are scanning and/or transmission electron microscopy. Spectroscopy and mass spectrometry can also be coupled with microscopic analysis for detailed compositional investigations.
