Non-targeted analysis for organic components of microplastic leachates

Science of The Total Environment, 2022
Organic components of microplastic leachates were investigated in an integrated non-targeted analysis study that included statistical analysis on leachates generated under different leaching scenarios. Leaching experiments were undertaken with simulated gastric fluid (SGF), river water, and seawater with common polymer types, including polyethylene ...

Uncertainty estimation strategies for quantitative non-targeted analysis

Analytical and Bioanalytical Chemistry, 2022
Non-targeted analysis (NTA) methods are widely used for chemical discovery but seldom employed for quantitation due to a lack of robust methods to estimate chemical concentrations with confidence limits. Herein, we present and evaluate new statistical methods for quantitative NTA (qNTA) using high-resolution mass spectrometry (HRMS) data from EPA's Non-

The chemical space for non-target analysis

TrAC Trends in Analytical Chemistry, 2017
Abstract The review describes chemical space, i.e. the set of known and possible compounds, and presents the use of corresponding chemical data in non-target analysis. Its implementation is briefly considered. General and dedicated chemical databases are outlined. Citation and co-citation of chemical compounds in databases are considered.

An Introduction to the Benchmarking and Publications for Non-Targeted Analysis Working Group

Analytical Chemistry, 2021
Non-targeted analysis (NTA) encompasses a rapidly evolving set of mass spectrometry techniques aimed at characterizing the chemical composition of complex samples, identifying unknown compounds, and/or classifying samples, without prior knowledge regarding the chemical content of the samples.
