Non-targeted analysis of unexpected food contaminants using LC-HRMS [PDF]
Analytical and Bioanalytical Chemistry, 2018 A non-target analysis method for unexpected contaminants in food is described. Many current methods referred to as "non-target" are capable of detecting hundreds or even thousands of contaminants. However, they will typically still miss all other possible contaminants. Instead, a metabolomics approach might be used to obtain "true non-target" analysis.

Optimization and validation of a LC-HRMS method for aflatoxins determination in urine samples [PDF]
Mycotoxin Research, 2020 Mycotoxins' exposure by inhalation and/or dermal contact can occur in different branches of industry especially where heavily dusty settings are present and the handling of dusty commodities is performed. This study aims to explore the possible contribution of the occupational exposure to aflatoxins by analysing urine samples for the presence of ...

Metabolism Profile of Mequindox in Sea Cucumbers In Vivo Using LC-HRMS
Antibiotics, 2022 In this work, the metabolism behavior of mequindox (MEQ) in sea cucumber in vivo was investigated using LC-HRMS. In total, nine metabolites were detected and identified as well as the precursor in sea cucumber tissues. The metabolic pathways of MEQ in sea cucumber mainly include hydrogenation reduction, deoxidation, carboxylation, deacetylation, and ...

Critical assessment of the chemical space covered by LC-HRMS non-targeted analysis
Environmental Science & Technology, 2023 Non-targeted analysis (NTA) has emerged as a valuable approach for the comprehensive monitoring of chemicals of emerging concern (CECs) in the exposome. The NTA approach can theoretically identify compounds with diverse physicochemical properties and sources.
