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

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