Aerodynamic thermal breakup droplet ionization (ATBDI) offers a novel approach for mass spectrometric drug analysis. This method effectively analyzes illicit substances like cocaine and heroin, and opium alkaloids.
Area of Science:
- Analytical Chemistry
- Forensic Science
Background:
- Mass spectrometry is crucial for drug analysis.
- Traditional ionization methods may have limitations for complex samples.
Purpose of the Study:
- To evaluate Aerodynamic Thermal Breakup Droplet Ionization (ATBDI) for drug analysis.
- To compare ATBDI with Electrospray Ionization (ESI).
Main Methods:
- ATBDI was applied to cocaine, heroin, and opium alkaloids.
- Analyzed temperature dependence of ATBDI signal intensities.
- Compared ATBDI with ESI for selected compounds and real-world samples.
Main Results:
