Abstract: |
With the improvement of mass accuracy in mass spectrometry and the expansion of the material database, the high throughput non targeted screening techniques developrapidly, which provides an effective means for the analysis and identification of pollutants in complex environmental media. This paper summarizes the advances of non targeted screening techniques [gas chromatography high resolution mass spectrometry (GC HRMS) and liquid chromatography high resolution mass spectrometry (LC HRMS) ] in environmental sample analytical methods, including sample pretreatment methods, non targeted analysis platforms, data analysis and current challenges. The applications of non targeted screening techniques for analyzing water, sediment and soil samples are reviewed as well, and the existing problems and application prospect are promoted. |
