EPA Method 1633 and How It Can Help You with Your PFAS Testing Needs.

/in /by

What is EPA Method 1633?

EPA Method 1633 is a draft method developed by the US Environmental Protection Agency (EPA) to measure 40 different types of PFAS in various environmental matrices, such as water, soil, biosolids, and tissue. The method uses liquid chromatography-tandem mass spectrometry (LC-MS/MS) to separate and detect the PFAS compounds in the samples. The method covers nine compound classes of PFAS, including linear and branched isomers. It also provides guidance on sample collection, preservation, extraction, cleanup, and quality control.

EPA Method 1633 is still in the draft stage and has not been finalized or approved for regulatory use. However, it is expected to provide a standardized and comprehensive approach for measuring PFAS in various environmental matrices. The method is also intended to complement other existing or proposed methods for PFAS analysis, such as EPA Method 537.1 for drinking water.

How Does EPA Method 1633 Differ from EPA Method 537.1?

EPA Method 537.1 is the current method for PFAS testing in drinking water. It was first published in 2009 and revised in 2018. EPA Method 537.1 can measure 18 PFAS compounds in drinking water using solid phase extraction (SPE) and LC-MS/MS.

EPA Method 1633 differs from EPA Method 537.1 in several ways, such as:

  • EPA Method 1633 can measure 40 PFAS compounds, including nine compound classes and linear and branched isomers, while EPA Method 537.1 can measure only 18 PFAS compounds.
  • EPA Method 1633 can test for PFAS in various environmental matrices, such as water, soil, biosolids, and tissue, while EPA Method 537.1 can only test for PFAS in drinking water.
  • EPA Method 1633 uses different sample collection, preservation, extraction, cleanup, and quality control procedures depending on the matrix type, while EPA Method 537.1 uses the same procedure for all drinking water samples.

How Can EPA Method 1633 Help You with Your PFAS Testing Needs?

Using EPA Method 1633 for PFAS testing can offer you several benefits and advantages, such as:

  • You can test for a wider range of PFAS compounds in various environmental matrices using a single method.
  • You can obtain more accurate and reliable results using a sensitive and selective analytical technique.
  • You can follow standardized and comprehensive procedures that ensure the quality and consistency of your data.
  • You can comply with the current and future regulatory requirements and guidelines for PFAS testing.
