Analysis of difluoroacetic acid and trifluoroacetic acid in drinking water sources
6 Aug 2023Trifluoroacetic acid (TFA) and difluoroacetic acid are ultra-short-chain per- and polyfluoroalkyl substances (PFAS) that have been found to be breakdown products of many pesticides. Pesticides, and therefore TFA, have the potential to contaminate drinking water supplies as they are applied to farmlands, gardens, and lawns making their way into groundwater and surface water systems. The German Federal Environment Agency (UBA) issued a guidance value for TFA in drinking water of 60 µg/L and a target value of 10 µg/L. In this application note from Phenomenex, explore a robust and reliable method for the determination of TFA from drinking water and mineral water well sources, using a Luna Omega 3 µm PS C18 column, by LC-MS/MS.

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.Environmental ContaminationContaminants in the environment are harmful chemicals that are present in the air, land and water. These include pesticides, pharmaceuticals, persistent organic pollutants (POPs) and many more.Environmental AnalysisEnvironmental analysis describes a variety of tests that determine the effect of chemicals, processes and particulates such as persistent organic pollutants (POPs) have on the environment.Drinking Water AnalysisAnalytical methods used to test the purity of drinking water include determining the level of contaminants abides to the level set by the Environmental Protection Agency (EPA).
