Among the organic compounds carried by PM2.5, polycyclic aromatic hydrocarbons are the most harmful, and it has strong mutagenic, carcinogenic and teratogenic effects. And bioaccumulative and persistent. Food safety is another hot spot of public concern. Non-food substances such as pesticides, polychlorinated biphenyls, plasticizers, and nitrosamines are highly carcinogenic and seriously endanger human health. Metabolomics is a research method that imitates the research of genomics and proteomics, quantitatively analyzes all metabolites in living organisms, and finds the relative relationship between metabolites and physiological changes. Metabolomics has demonstrated successful demonstration effects in disease analysis, drug research, plant and microbial gene function, and phenotypic research, making the discipline gradually shift from relative quantification to absolute quantification.
The application examples listed in the TSQ 8000 Series Mass Spectrometer Application Guide include the relevant analytical assays described above, for example, the determination of plasticizer residues in alcoholic products by triple quadrupole measurement-isotope internal standard quantitation. It can correct and eliminate the influence of operating conditions on the analysis results, improve the accuracy of the analysis results, and has the advantages of convenient operation, good selectivity, high sensitivity and wide linear range. Another example: In the determination of nitrosamines in food, Thermo Scientific has a patented powerful AutoSRM function, which requires only one sample vial containing the standard sample to be optimized, without manual modification, automatically optimizes the ion pair parameters. Automatically import the secondary ion pair parameters into the instrument method, saving manual input time and avoiding the errors.
Through the sharing of relevant application cases in this article, customers can learn more about the world's most advanced gas chromatography triple quadrupole mass spectrometer, TSQ 8000 series for the high-throughput target compound quantification, screening and common organic analysis.
