Journal ArticleDOI
Profiling cocaine by ATR-FTIR.
Marcelo Caetano Alexandre Marcelo,Kristiane de Cássia Mariotti,Marco Flôres Ferrão,Rafael S. Ortiz +3 more
TL;DR: In this article, five hundred and thirteen cocaine seizures of the State of Rio Grande do Sul (Brazil) were analyzed by Fourier transform infrared spectroscopy in the fingerprint region to profiling and evaluate the pharmaceutical products used as adulterants.
Journal ArticleDOI
Counterfeit Cialis and Viagra fingerprinting by ATR-FTIR spectroscopy with chemometry: Can the same pharmaceutical powder mixture be used to falsify two medicines?
Rafael S. Ortiz,Kristiane de Cássia Mariotti,Bruna Fank,Renata Pereira Limberger,Michel José Anzanello,Paulo Mayorga +5 more
TL;DR: The similarity match (SM) method is applied to demonstrate that a mixture of pharmaceutical powders deriving from a common origin may have been used to manufacture both counterfeit Cialis and Viagra tablets from distinct seizures.
Journal ArticleDOI
Fingerprinting of sildenafil citrate and tadalafil tablets in pharmaceutical formulations via X-ray fluorescence (XRF) spectrometry.
Rafael S. Ortiz,Kristiane de Cássia Mariotti,Nicolas V. Schwab,Guilherme P. Sabin,Werickson Fortunato de Carvalho Rocha,Eustáquio V.R. Castro,Renata Pereira Limberger,Paulo Mayorga,Maria Izabel M. S. Bueno,Wanderson Romão +9 more
TL;DR: XRF has advantageous features like multielemental capability, good detectivity, high precision, short analysis times, and is nondestructive, which makes it suitable to be extended to a great variety of samples.
Journal ArticleDOI
Near infrared spectroscopy combined with chemometrics for growth stage classification of cannabis cultivated in a greenhouse from seized seeds.
Bruna Tassi Borille,Marcelo Caetano Alexandre Marcelo,Rafael S. Ortiz,Kristiane de Cássia Mariotti,Marco Flôres Ferrão,Renata Pereira Limberger +5 more
TL;DR: The growth stage of cannabis can be predicted by NIR spectroscopy and chemometric tools in the early stages of indoor cannabis cultivation in Brazil.
Journal ArticleDOI
Determination of amphetamine-type stimulants in oral fluid by solid-phase microextraction and gas chromatography–mass spectrometry
Daniele Zago Souza,Daniele Zago Souza,Paula Otero Boehl,Eloisa Comiran,Kristiane de Cássia Mariotti,Flavio Pechansky,Paulina do Carmo Arruda Vieira Duarte,Raquel Brandini De Boni,Pedro Eduardo Fröehlich,Renata Pereira Limberger +9 more
TL;DR: The validated method can be easily automated and then used for screening and confirmation of amphetamine-type stimulants in drivers' oral fluid and the goodness-of-fit concerning the ordinary least squares model in the statistical inference of data has been tested through residual plotting and ANOVA.
