Methods Used
- Thawing and vortexing urine samples.
- Centrifugation and preparation of samples with internal standards.
- Capillary conditioning and setup of CE-MS parameters.
- Data acquisition and analysis using specific software settings.
Main Results
- 30 resolved peaks from 10 independent drug mixture samples were detected.
- Two isobaric opioids were fully resolved into 20 distinct peaks.
- Two amphetamine positional isomers were distinguished effectively.
- No sample carryover was observed during the analysis.
Conclusions
- The MSI-CE-MS method provides a comprehensive approach to drug screening.
- It allows for the detection of a wide range of drugs with high accuracy.
- This method has potential applications in various research areas.
