Methods and systems for performing mass spectrometry are provided herein. The method includes ionizing one or more compounds to generate ions, passing the ions into an ion mobility spectrometer, providing ozone, reacting the ions with ozone to produce ozone-induced fragment ions, and performing mass analysis and detection of the ozone-induced fragment ions. The system can comprise an ion source for ionizing one or more compounds to generate ions, an ion mobility spectrometer for receiving and separating the ions, an ozone supply for introducing ozone into the system; a reaction region for reacting the ions with the ozone to produce ozone- induced fragment ions, and a mass spectrometer for performing mass analysis and detection of the ozone-induced fragment ions. |
