Autor: Henrique Marcelo G. Pereira, Karina M. Cavalcante, Fernanda B. Scalco, Maria Lúcia Costa de Oliveira, Francisco Radler de Aquino Neto, Vinicius Figueiredo Sardela, Deyvison R. Silva, Ruth Ellen Simoni
Publikováno v: Drug Testing and Analysis. 7:967-970
Glycerol is a naturally occurring polyol in the human body, essential for several metabolic processes. It is widely used in the food, pharmaceutical, and medical industries and in clinical practice as a plasma volume expander (PVE). Athletes, however

Optimization of an online heart-cutting multidimensional gas chromatography clean-up step for isotopic ratio mass spectrometry and simultaneous quadrupole mass spectrometry measurements of endogenous anabolic steroid in urine
Autor: Thomas Piper, Francisco Radler de Aquino Neto, Fábio Azamor de Oliveira, Alessandro Casilli, Henrique Marcelo G. Pereira, Monica Costa Padilha, Mario Thevis
Publikováno v: Drug testing and analysis. 8(11-12)
Measuring carbon isotope ratios (CIRs) of urinary analytes represents a cornerstone of doping control analysis and has been particularly optimized for the detection of the misuse of endogenous steroids. Isotope ratio mass spectrometry (IRMS) of appro

Consequences of the formation of 3,4-dimethyl-5-phenyl-1,3-oxazolidine on the analysis of ephedrines in urine by gas chromatography and a new method for confirmation as N-trifluoroacetyl-O-t-butyldimethylsilyl ether derivatives
Autor: F.R. Aquino Neto, Henrique Marcelo G. Pereira, Vinicius Figueiredo Sardela, Patrícia D. O. Sardela
Publikováno v: Journal of chromatography. A. 1218(9)
The compound 3,4-dimethyl-5-phenyl-1,3-oxazolidine can appear as an artifact during the gas chromatographic analysis of ephedrines. Its presence is a risk for doping control and forensic analyses. An evaluation about the consequences of its formation
