Advances in Analytical Chemistry and Mass Spectrometry to Support a Sustainable and Circular Economy

  • Recent advances in analytical chemistry have significantly supported efforts to realize a sustainable circular economy and circular chemistry. By enabling rapid materials analysis and characterization of materials transformation throughout their life cycle, analytical methods are playing a key role in supporting waste reduction, resource recovery, pollution monitoring, and sustainable manufacturing. In this presentation, recent developments in analytical chemistry and analytical instrumentation to support a sustainable and circular economy will be reviewed and selected contributions from our laboratories will be discussed. For example, high-resolution mass spectrometry combined with chromatography is an indispensable tool for the identification and characterization of plastics. To support the transition from linear to circular chemistry, whichs prioritizes reuse, recycling, and resource efficiency, accurate and detailed chemical information about plastic materials is essential.

In this presentation, recent developments in analytical chemistry and analytical instrumentation to support a sustainable and circular economy will be reviewed and selected contributions from our laboratories will be discussed. For example, high-resolution mass spectrometry combined with chromatography is an indispensable tool for the identification and characterization of plastics. To support the transition from linear to circular chemistry, whichs prioritizes reuse, recycling, and resource efficiency, accurate and detailed chemical information about plastic materials is essential. Here, targeted and non-targeted screening approaches help to characterize, for example, the quality and safety of recycled plastics. In addition, green analytical chemistry has emerged as a topic of interest, emphasizing the use of solvent-free and low-energy methods to minimized environmental impact during analysis. Here, ambient desorption/ionization high-resoluton mass spectrometry (ADI-MS) is considered a very attractive tool because it dos not require chromatography or large amounts of solvent, reduces sample preparation time, and produces virtually no chemical waste. Here, a solvent-free, plasma-based ADI-MS method is presented, which was carefuly developed for the direct identification and fast screening of per- and polyfluoroalkyl substances (PFAS). PFAS are a large class of thousands of synthetic chemicals that are used worldwide. However, growing environmental and human health concerns in the last two decades have led to more stringent regulatory requirements and the development of quantitative analytical methods for PFAS detection. Today, standardized and powerful methods exist, e.g., for the determination PFAS in water, sludge, compost, soil, and drinking water. While liquid chromatography coupled to tandem mass spectrometry (LC-MS/MS) is often used, sample preparation, solvent consumption, and total analysis times can be challenging. Here, ADI-MS is considered interesting, because it requires only minimal sample preparation and little solvent consumption. In this work, a plasma-based pin-to-capillary flowing atmospheric-pressure afterglow source (FAPA) is used for the direct desorption/ionization of PFAS from thin-layer chromatography (TLC) plates. Selected PFAS samples were directly probed on functionalized TLC surfaces without a preceding planar chromatography step. In addition, direct analysis of PFAS mixtures and selected matrices was performed with little solvent consumption, no sample preparation and short analysis time.zeige mehrzeige weniger
