 Atmospheric-pressure laser ionization

Atmospheric-pressure laser ionization (APLI) is an analytical technique used to generate and detect ions from analytes (compounds of interest) at or near atmospheric pressure, typically for the purpose of mass spectrometry. This method allows for the direct ionization of samples without the need for advanced vacuum systems or complex ionization conditions that are typical in traditional mass spectrometric techniques. **Key aspects of Atmospheric-pressure laser ionization include:** 1.
