Dinotefuran (DNT) belongs to the third-generation neonicotinoid pesticides, which are among most common residuals in a variety of food commodities. To guarantee accurate quantification and traceability results samples, certified reference materials (CRMs) indispensable benchmark. In this work, DNT CRM was characterized its purity assessed by two independent methods, including mass balance (MB) quantitative nuclear magnetic resonance spectroscopy (qNMR). The fraction moisture 0.33 mg/g,...
Selenium-enriched yeast possesses the unique ability of transforming chemical selenium, such as sodium selenite, into a biologically active form, which mitigates its toxic effects on human body. The transformation product this process, selenomethionine, can be safely and effectively absorbed utilized by body; hence, it has been spiked selenium-enriched supplement. This study employs two distinct measurement strategies to determine selenomethionine content in candidate reference materials,...
It is well established that arsenic (As) has many toxic compounds, and in particular, inorganic As (iAs) been classified as a type-1 carcinogen. The measuring of species rice flour great importance since staple the diet countries major contributor to intake Asian diet. In this study, several solvents techniques for extraction from samples prior their analysis by HPLC-ICP-MS were investigated. methods examined efficiency extracting various arsenicals certified reference material, NMIJ-7532a,...
