Membrane inlet mass spectrometry (MIMS) for analysis of water disinfection byproducts: Recent advances

This review presents progress related to the use of MIMS for DBP analysis in water since 2010. We highlight new developments with focus upon instrumentation, quantification and new applications within swimming pools, water treatment, mechanistic studies, and kinetic modelling. Focus areas such as high resolution mass spectrometry for differentiation between isobaric isomers, analysis of hydrophilic and or less volatile DBPs using condensed phase MIMS and quantification based upon univariate and multivariate mathematical algorithms are reviewed. Today, MIMS has proven to be a valuable management tool allowing implementation of water treatment strategies focusing on DBP mitigation during water treatment.& COPY; 2023 The Authors.
