Determination of moxidectin in serum by liquid chromatography-tandem mass spectrometry and its application in pharmacokinetic study in lambs. Author(s): BAPTISTA, R. C.; FERNANDES, M. A. M.; GILAVERTE, S.; QUEIROZ, S. C. do N. de; ASSALIN, M. R.; FERRACINI, V. L.; MONTEIRO, A. L. G.; REYES, F. G. R. 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... ... Repository: BDPA Publication year: 2017
Development and validation of a method for the analysis of Ochratoxin A in roasted coffee by liquid chromatography/electrospray-mass spectrometry in Tandem (LC/ESI-MS/MS). Author(s): BANDEIRA, R. D. C. C.; UEKANE, T. M.; CUNHA, C. P. da; GEAQUINTO, L. R. O.; CUNHA, V. S.; CAIXEIRO, J. M. R.; GODOY, R. L. O.; CRUZ, M. H. C. de la. A method using LC/ESI-MS/MS for the quantitative analysis of Ochratoxin A in roasted coffee was described. Linearity was demonstrated (r = 0.9175). The limits of detection and quantification were 1.0... ... Repository: BDPA Publication year: 2012
