“…Since 2D gas chromatography (2D GC) provides mass sensitivity, simple sample preparation, and easy identification of compounds, it was a method of our choice. The 2D GC–MS has found application in the analysis of lignin degradation products [7], fuel biodegradation [8], food [9,10], and essential oil [11] analysis.…”

The 2D GC-MS has found application in the analysis of lignin degradation products [7], fuel biodegradation [8], food [9,10], and essential oil [11] analysis. The aim of this research was the screening of semi-VOCs in wheat and pea using 2D GC-MS to investigate their qualitative changes after their treatment with 200 mg L −1 uncoated (CeO 2 ) and glucose-, levan-, and pullulancoated nCeO 2 (glucose-coated cerium oxide nanoparticles (G-CeO 2 ), levan-coated cerium oxide nanoparticles (L-CeO 2 ), and pullulan-coated cerium oxide nanoparticles (P-CeO 2 )) during three weeks-growth in hydroponics.…”

Literature data about semi‐volatile organic compounds in plants and the effect of cerium oxide nanoparticles on them are scarce. Surface modification of nanoparticles may change nanoparticle‐environment interaction, and therefore affects compounds in plants. In this research, uncoated and glucose‐, levan‐, and pullulan‐coated cerium oxide nanoparticles were used for wheat and pea treatment during the growth. The aim was the screening of semi‐volatile organic compounds from plants’ shoots using comprehensive two‐dimensional gas chromatography–mass spectrometry, a powerful separation technique allowing to reach unique separation resolution, and investigation of qualitative changes after the treatment with coated cerium oxide nanoparticles. The results were analyzed by the identification of individual peaks and fingerprint analysis by image processing. Wheat samples contained a higher number of semi‐volatile organic compounds (108) compared to pea (77) but were less affected by the treatments with coated nanoparticles. The highest number of compounds was detected in wheat after the treatment with levan‐ and pullulan‐coated nanoparticles, and in pea after treatment with levan‐coated nanoparticles. This article reports a successful application of a semi‐volatile organic compounds profile presented only as categorical variables and unique fingerprint images for the inter‐cultivar recognition. This method may be useful in screening nanoparticles’ effects on different plants.

“…The use of GC × GC for environmental analysis is expected to be especially effective for simultaneous analysis of compounds with multiple isomers and analogs, such as hydroxylated polychlorinated biphenyls (HO-PCBs) (Hashimoto et al, 2010;Rezek et al, 2012) and chlorinated paraffins (Eljarrat and Barcelo, 2006;Muscalu et al, 2017), which pose environmental risks but are difficult to measure. We have been developing methods using GC × GC / ToFMS (Fushimi et al, 2012;Hashimoto et al, 2008Hashimoto et al, , 2011Ieda et al, 2019;Lješević et al, 2019;Ochiai et al, 2011) and software tools to analyze the data generated (Hashimoto et al, 2013;Zushi et al, 2013Zushi et al, , 2014Zushi et al, , 2015Zushi et al, , 2017Zushi and Hashimoto, 2018) for environmental investigations.…”

The notable challenges facing non-target environmental monitoring are the improvement of the reproducibility of extraction rates and the selection of internal standards for concentration correction. In the present study, a rapid and comprehensive analytical method, which we had developed in a previous study, greatly reduces the need for pretreatment. The method was applied to the actual measurement of river water. The water samples were divided into five sub-samples and analyzed by sorptive extraction using a magnetic stirrer coated with polydimethyl siloxane. Direct and whole sample extracts were determined by thermal desorption/comprehensive two-dimensional gas chromatography/ time-of-flight mass spectrometry. Approximately 2,000 of the components were detected, and 80 of these components were selected for statistical evaluation in order to investigate the stability of the method and the ability to detect differences among samples. The effectiveness of this technique was confirmed by statistical methods, including the Kruskal-Wallis test, which is used to examine nonparametric multigroup comparisons and with which once can detect differences by comparing raw data obtained as precise mass measurements without the need to identify the substance itself. In brief, we show that changes in signal intensity of any unknown substance can be detected. We note that variations in data (retention time, mass spectrum, and signal intensity) affect the ability to detect differences. The accuracy of each therefore had to be improved to enable sensitive and precise detection.
