Comprehensive profiling of environmental contaminants in surface water using high-resolution GC/Q-TOF
13 Apr 2021The use of accurate mass high-resolution MS (HRMS) techniques to characterize known and unknown pollutants in a sample is gaining in popularity. However, several environmental contaminants are low molecular weight, volatile, or nonpolar, making them much more amenable to analysis by GC rather than LC.
In this application note, Agilent Technologies demonstrate a workflow using an accurate mass high-resolution GC/Q-TOF for profiling environmental contaminants in samples of interest.

Environmental Monitoring and TestingEnvironmental monitoring and testing uses handheld portable analyzers, kits, spectrometers or chromatography systems for air, water, soil, food and other sample testing. Useful features of analyzers such as BOD and COD include portability, easy calibration, automation and sensitivity. Environmental test kits for pH, water, moisture, etc, should be accurate, sensitive, reliable, fast and easy to use.GC-MS GC-MS (gas chromatography-mass spectrometry) instruments and equipment are used to separate, quantify and identify mixtures of small and volatile compounds, such as polycyclic aromatics, fatty acids and alcohols. Often used in drug detection, forensic investigation and environmental analysis for pesticides and contaminants, GC-MS is a powerful addition to your lab’s analytical capabilities. GC-MS/MS instruments equipped with a qTOF or triple quadrupole analyzers can give greater sensitivity and resolution to your analysis.

These include pesticides, pharmaceuticals, persistent organic pollutants (POPs) and many more.
