Our Solutions/Mixtures for EPA-1633 Method
These mixtures, such as EPA-1633STK, contain quantitative isomeric mixtures of PFAS that were not previously available on the market. They can be diluted and/or combined with other mixtures prepared by Wellington Laboratories to obtain the spiking and calibration solutions recommended by the method: MPFAC-HIF-ES and MPFAC-HIF-ES.
The use of these mixtures ensures greater precision and reliability in the analysis of PFAS analysis, making it easier to implement EPA-1633 in a variety of environmental contexts.
Thanks to these innovations, laboratories can now carry out more complete and accurate analyses , contributing to better management of the environmental risks associated with PFAS.
All our mixtures are available as 1.2 mL solutions in methanol.

EPA Method 1633 is a standardised analytical procedure for detecting and quantifying PFAS in non-drinking water matrices. Developed by the US Environmental Protection Agency (EPA), this method uses liquid chromatography coupled with mass spectrometry (LC-MS/MS). It can identify and measure up to 40 different PFAS compounds. This method is therefore essential for monitoring PFAS in various non-drinking water matrices, helping to assess the risks associated with these persistent contaminants.
