A data independent acquisition all ion fragmentation mode tool for the suspect screening of natural toxins in surface water

open access: yesMethodsX, 2021
Among natural freshwater pollutants, cyanotoxins, mycotoxins, and phytotoxins are the most important and less studied. Their identification in surface water is challenging especially cause of the lack of standards and established analytical parameters ...

Suspect Screening Analysis of Chemicals in Consumer Products [PDF]

open access: yesEnvironmental Science & Technology, 2018
A two-dimensional gas chromatography-time-of-flight/mass spectrometry (GC×GC-TOF/MS) suspect screening analysis method was used to rapidly characterize chemicals in 100 consumer products-which included formulations (e.g., shampoos, paints), articles (e.g., upholsteries, shower curtains), and foods (cereals)-and therefore supports broader efforts to ...

Machine Learning for Absolute Quantification of Unidentified Compounds in Non-Targeted LC/HRMS

open access: yesMolecules, 2022
LC/ESI/HRMS is increasingly employed for monitoring chemical pollutants in water samples, with non-targeted analysis becoming more common. Unfortunately, due to the lack of analytical standards, non-targeted analysis is mostly qualitative. To remedy this,
