Atmospheric organic aerosols (OAs) are among the most complex environmental matrices known. Given OAs have well documented atmospheric and health effects, it is crucial to understand complexity composition of this matrix. On quest unravel information, advanced analytical approaches been developed for characterization complexity. This Perspective revisits important state-of-the-art multidimensional strategies, namely those that use a second or third dimension in spectroscopic, spectrometric, chromatographic methods, targeted untargeted profiling from both outdoor indoor environments. insight also comments on major challenges ahead concerning analysis, including processing extraction chemical information voluminous amount data generated approaches.

Comprehensive two-dimensional gas chromatography (GC×GC) is a mature analytical technique with far greater separation capability than conventional one-dimensional methods. Atmospheric organic aerosols are comprised of diverse range substances which challenge analysis, and for the method has proved very suitable. The review outlines basic principles separation, instrumentation, including detectors. Time-of-flight mass spectrometry offers many advantages, especially unknown mixtures, included use low high energy electron impact ionisation. available methods data reduction analysis outlined. GC×GC may be used in either targeted or untargeted modes, studies have covered wide analytes, compound groups. Most common hydrocarbons, polycyclic aromatic hydrocarbons (PAH), but other work oxygenates, chlorinated nitrogen compounds, industrial chemicals consumer products sampled across environments.

Atmospheric particulate matter (PM) is a complex mixture with wide range of sources, but only limited proportion can be identified by existing analytical techniques. Comprehensive two-dimensional gas chromatography-mass spectrometry (GC × GC-MS) couples the advantages on high resolution, sensitivity, and peak capacity chromatography, together mass accuracy acquisition frequency time-of-flight (TOFMS). GC GC-MS has been gradually applied analysis environmental organic pollutants. This review introduces principles MS discusses its application compounds in atmospheric PM last two decades, so as to provide an outlook future trends this research frontiers. The synthesizes findings for analyzing pollutants PM, covering operational coupling TOFMS enhance speed. significantly improved identification PM-associated offering superior separation, capacity, detection sensitivity. technique enabled discovery previously unresolvable enhanced source apportionment PM. Despite advantages, widespread studies hindered challenges such data processing, instrument cost, standardization issues. offers separation pollutants, making it invaluable applications. Emerging technologies, machine learning, will capabilities broaden
