How Does EI Compare to Other Ionization Techniques?
Compared to other ionization techniques such as chemical ionization (CI) and electrospray ionization (ESI), EI is known for its ability to produce simple and reproducible mass spectra. However, it is less suited for the analysis of large, non-volatile, or thermally unstable molecules. CI, on the other hand, produces less fragmentation and is better for analyzing complex organic compounds, while ESI is particularly useful for studying large biomolecules and non-volatile compounds. Each technique has its own strengths and limitations, and the choice of ionization method depends on the specific requirements of the catalytic study.
