electron ionization (ei)

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.
