In present day organic chemistry spectroscopic technics (NMR, both 1H and 13C), mass spectrometry and chromatographic procedures have replaced EA as the primary technique for structural determination, although it still gives very useful complementary information.
在今天，有机化学光谱技术（如核磁共振(NMR)，1H和13C）中，质谱法和色谱法已经取代元素分析作为结构测定的主要技术，尽管它仍然提供非常有用的补充信息。
