Nontargeted screening (NTS) utilizing liquid chromatography electrospray ionization high-resolution mass spectrometry (LC/ESI/HRMS) is increasingly used to identify environmental contaminants. Major differences in the efficiency of compounds ESI/HRMS result widely varying responses and complicate quantitative analysis. Despite an increasing number methods for quantification without authentic standards NTS, approaches are evaluated on limited diverse data sets with chemical coverage collected...
This research presents an analytical technology for highly efficient, high-resolution, and high-yield fractionation of compounds after gas chromatography (GC) separations. The is straightforward, does not require sophisticated cold traps or adsorbent traps, allows collecting large numbers fractions during a GC run. based on direct infusion carrier solvent at the end column, where takes place in oven. Pentane hexane used as showed good results. Acetonitrile also results more polar solvent....
In this study we compare two parallel analytical methods while also testing a microplastics mitigation method. We assess the effectiveness of bubble curtain to reduce in wastewater treatment plant (WWTP)-effluent canal during course six months (>70 samples) using techniques: laser direct infrared (LDIR) and optical microscopy (OM) covering size range 0.02 5 mm. Comparison strategies shows similar trends, fluctuations, correlating particle fibre numbers. However, absolute values particles...
Abstract In fields such as food safety and environmental chemistry, ensuring is greatly challenged by large numbers of unknown substances occurring. Even with current state‐of‐the‐art mass spectrometers, dealing nonidentified a very laborious process it includes structure elucidation vast number unknowns, which only fraction may be relevant. Here, we present an exploration prioritization approach based on high‐resolution spectrometry. The method uses algorithm‐based precursor/product‐ion...
In this month's Featured Article Eelco Pieke and his colleagues from the National Food Institute, Technical University of Denmark, discuss some timely issues in objective practical assessment food environmental safety. As authors rightly suggest, our increasingly unpredictable world, even with powerful analytical tools at disposal, realistic risk is a challenge. any given scenario, an almost limitless array unknown substances can ‘contaminate’ environment, depending on structure, properties...
