“MS-Ready” structures for non-targeted high-resolution mass spectrometry screening studies [PDF]

open access: yesJournal of Cheminformatics, 2018
Chemical database searching has become a fixture in many non-targeted identification workflows based on high-resolution mass spectrometry (HRMS). However, the form of a chemical structure observed in HRMS does not always match the form stored in a ...

Suspect and non-targeted screening of chemical pollutants in Botswana's aquatic environments

open access: yesEmerging Contaminants
Chemical pollution in the aquatic systems of Botswana has been sparsely studied despite its potential ecological importance. Here, we perform a study of water samples collected from 13 locations distributed across Botswana to obtain the first overview of

Bladder cancer biomarker screening based on non-targeted urine metabolomics [PDF]

open access: yesInternational Urology and Nephrology, 2021
Bladder cancer is one of the most common malignancies of the urinary system, and its screening relies heavily on invasive cystoscopy, which increases the risk of urethral injury and infection. This study aims to use non-targeted metabolomics methods to screen for metabolites that are significantly different between the urine of bladder cancer patients ...

Quantification for non-targeted LC/MS screening without standard substances [PDF]

open access: yesScientific Reports, 2020
AbstractNon-targeted and suspect analyses with liquid chromatography/electrospray/high-resolution mass spectrometry (LC/ESI/HRMS) are gaining importance as they enable identification of hundreds or even thousands of compounds in a single sample. Here, we present an approach to address the challenge to quantify compounds identified from LC/HRMS data ...
