Estimation of synthetic route of methamphetamine samples seized in China by direct analysis in real time with high-resolution mass spectrometry and chemometric analysis of organic impurities

Autor: Zhendong Hua, Wu Zhongping, Huichao Yin, Chen Liang, Yurong Zhang, Ru Lian, Guiliang Chen, Rong Wang, Xuezi Cui

Publikováno v: Microchemical Journal. 159:105481

A direct analysis in real time combined with high-resolution mass spectrometry (DART-HRMS) method was established to quickly detect organic impurities in methamphetamine (MA) samples. A partial least-squares discriminant analysis (PLS-DA) model was e

Correlation analysis between cocaine samples seized in China by the rapid detection of organic impurities using direct analysis in real time coupled with high-resolution mass spectrometry

Autor: Ru Lian, Rong Wang, Xuezi Cui, Chen Liang, Guiliang Chen, Yurong Zhang

Publikováno v: International Journal of Mass Spectrometry. 444:116188

A direct analysis in real time (DART) coupled with high-resolution mass spectrometry (HRMS) method was established to detect organic impurities in cocaine samples seized in China. This approach allowed discrimination between linked and unlinked seizu
