Autor: Ivette Torres-Negrón de Jeanville, Patrick M. Jeanville, Estela S. Estapé

Publikováno v: International Journal of Mass Spectrometry. 227:247-258

We investigated the effect of common chromatography eluents and additives on the positive ion responses of ecgonine methyl ester (EME), benzoylecgonine (BZE), and cocaine (COC) using electrospray ionization (ESI). Primarily [M+H]+ ions were observed,

Rapid Confirmation/Quantitation of Ecgonine Methyl Ester, Benzoylecgonine, and Cocaine in Urine Using On-Line Extraction Coupled with Fast HPLC and Tandem Mass Spectrometry

Autor: Patrick M. Jeanville, Arturo Martí, Ivette Torres-Negron, Estela S. Estapé

Publikováno v: Journal of Analytical Toxicology. 25:69-75

A rapid, rugged, and highly specific assay for the quantitation of cocaine (COC) and especially its primary metabolites benzoylecgonine (BZE) and ecgonine methyl ester (EME) in human urine has been established. Here, we investigated the use of on-lin

Direct determination of ecgonine methyl ester and cocaine in rat plasma, utilizing on-line sample extraction coupled with rapid chromatography/quadrupole orthogonal acceleration time-of-flight detection

Autor: Theodore J Baird, Patrick M. Jeanville, James H. Woods, Estela S. Estapé

Publikováno v: Journal of Pharmaceutical and Biomedical Analysis. 23:897-907

Our current experiments assess the applicability of on-line sample extraction with coupled rapid chromatography systems to quadrupole orthogonal acceleration time-of-flight (Q-TOF) detection for the quantitative analysis of cocaine (COC), and ecgonin

Potential Contributions of Data Analysis Methods to the Development of Nondestructive Testing and in Particular Acoustic Emission

Autor: M. Jeanville, M. Cherfaoui, J. Roget

Data Analysis Methods are very powerful techniques combining Mathematics, Statistics and Data Processing. They have two objectives: – to extract the key-information within large data tables, – to give a synthetic display of experimental data, in
