Determination of moxidectin in serum by liquid chromatography-tandem mass spectrometry and its application in pharmacokinetic study in lambs. Abstract: The widespread use of moxidectin (MOX), a parasiticide used in the sheep breeding, has induced the parasite resistance in Brazilian farms. As a consequence, the farmers often increase the do... ... Repositório: BDPA Ano de publicação: 2017
Determination of herbicides in human urine by liquid chromatography-mass spectrometry with electrospray ionization. Repositório: BDPA Ano de publicação: 2006
A rapid ultrasound-assisted dispersive liquid-liquid microextraction followed by liquid chromatography coupled to a mass spectrometry for determination of artemisinin in tilapia muscle. Intensive aquaculture represents stressful conditions for fish and can trigger diseases that negatively affect their performance and survival. Fish production requires greater control, with improved h... ... Repositório: BDPA Ano de publicação: 2019
Determination of pesticides in water by liquid chromatography-(Electrospray Ionization)-mass spectrometry (LC-ESI-MS). A method for determination of a selected group of pesticides in water (tap and ground water) was developed using liquid chromatography-(electrospray ionization)-mass spectrometry (LC-ESI-MS). The pest... ... Repositório: BDPA Ano de publicação: 2004

Verification of the selectivity of a liquid chromatography method for determination of stilbenes and flavonols in red wines by mass spectrometry. Quantification of bioactive phenols, like stilbenes and flavonols (SaF), has been conducted to evaluate the nutraceutical potential of red wines. However, there is still a lack of full validated, fast... ... Repositório: BDPA Ano de publicação: 2016
Flavan-3-ol (Flavanol) identification and quantitation by high performance liquid chromatography coupled with mass spectrometry (HPLC-MSn). Flavan-3-ols are widely distributed in higher plants, such as grapes, located in the skins and seeds, being transferred to the wine during winemaking. They are responsible for specific sensory propert... ... Repositório: BDPA Ano de publicação: 2023
