Cocaine classification using alkaloid and residual solvent profiling

Cocaine classification using alkaloid and residual solvent profiling

Highlights • Cocaine classification was evaluated using alkaloid and residual solvent profiling. • Residual solvent profiles exhibit higher discrimination power than alkaloid profiles. • GLM, LDA and QDA were used to establish residual-solvent-weighted models. • A residual-solvent-weighted model exh...

Zusammenfassung:Highlights • Cocaine classification was evaluated using alkaloid and residual solvent profiling. • Residual solvent profiles exhibit higher discrimination power than alkaloid profiles. • GLM, LDA and QDA were used to establish residual-solvent-weighted models. • A residual-solvent-weighted model exhibited optimal classification.
