Determinação de As e Se em fígado bovino por ICP-MS utilizando ácido fórmico diluído no preparo de amostra. A crescente necessidade de produção de alimentos em larga escala requer o desenvolvimento de métodos rápidos e eficientes para a determinação de contaminantes. Repository: BDPA Publication year: 2012
Emprego de extração assistida por radiação micro-ondas e padrão de interferência para especiação de arsênio por HPLC-ICP-MS. Repository: BDPA Publication year: 2011
Avaliação de diferentes preparos de amostra para especiação de arsênio em tecido vegetal por HPLC-ICP-MS com o emprego de padronização interna com espécie poliatômica. Repository: BDPA Publication year: 2011
Determination of selenium in bovine semen by ICP-MS using formic acid for sample preparation. Determination of Se by inductively coupled plasma mass spectrometry (ICP-MS) can be difficult due to spectral interferences; however, these interferences can be eliminated by using collision-reaction... ... Repository: BDPA Publication year: 2017
Determination of elemental impurities in acyclovir ointment and raw materials using microwave acid digestion (MW-AD) and ICP-MS. Inorganic elements present in pharmaceutical products were determined by inductively coupled plasma-mass spectrometer (ICP-MS), employing microwave acid digestion as a sample preparation method. The m... ... Repository: BDPA Publication year: 2017
Evaluation of distribution and bioaccumulation of arsenic by ICP-MS in tilapia (Oreochromis niloticus) cultivated in different environments. The concentration of arsenic in tissues of tilapia was evaluated and an estimation of the risks associated with the consumption of this fish was done, taking into account the guidelines established by... ... Repository: BDPA Publication year: 2017
Avaliação da correção de sinais de fundo causados pelos íons diatômicos Ar2 + e CN+ em ICP-MS com interface CRI. Íons poliatômicos são formados durante os processos de atomização no plasma de argônio e transferência da nuvem atômica para o espectrômetro de massa, gerando interferências isobáricas. Esses íons são... ... Repository: BDPA Publication year: 2009
Chemical speciation of hexavalent chromium in organic fertilizer by LC-ICP-MS and spectrophotometry. Normative Instruction n. 7 of 04/12/2016 of the Ministry of Agriculture, Livestock and Food Supply (MAPA) defines the maximum values of contaminants allowed in organic fertilizers and soil conditioner... ... Repository: BDPA Publication year: 2023
Direct determination of arsenic compounds in beverages by HPLC-ICP-MS using interference standard methods. Repository: BDPA Publication year: 2012
Arsenic bioaccumulation and biotransformation in different tissues of Nile tilapia (Oreochromis niloticus): a comparative study between As(III) and As(V) exposure and evaluation of antagonistic effects of selenium. The speciation of arsenic in fish has been widely investigated, but bioaccumulation and biotransformation of inorganic As in different tissues of Nile tilapia (Oreochromis niloticus) are not fully und... ...
