Leveraging GC-MS and CIC as Complementary Techniques to LC-MS for a Comprehensive PFAS Solution

PFAS in Focus

Welcome to the PFAS in Focus, a comprehensive and exclusive 10-parts webinar series sponsored by Shimadzu, covering the basics and beyond about the analysis of Per- and Polyfluoroalkyl Substances (PFAS) in the environment. In these five webinars, our experts will demonstrate the suitability of various analytical techniques, such as LCMS, GCMS, CIC, and QTOF, for PFAS testing.

Join our experts, live or on-demand after the original air date, to demystify the challenges of PFAS analysis and gain the insights you need to:

• Manage PFAS contamination in your laboratory.
• Master standardized methods for PFAS testing.
• Discover new analytical workflows to maximize the performance of your instruments (LC-MS/MS, GCMS, CIC, QTOF) for PFAS analysis.

Who should attend:

• Environmental industry professionals and academics currently working on PFAS analysis or looking to establish the application in their labs.
• Representatives from drinking and wastewater utilities.
• LC–MS users from any field interested in expanding their applications to include PFAS testing.

Part 02: Leveraging GC-MS and CIC as Complementary Techniques to LC-MS for a Comprehensive PFAS Solution

The demand for per and polyfluoroalkyl substances (PFAS) analysis is growing. To date, there are several standardized PFAS methods. Most of these methods are based on Liquid Chromatography/Mass Spectrometry (LC/MS) techniques. However, LC/MS is not suitable to analyze all PFAS compounds because of the diverse physicochemical properties of chemicals within the PFAS family. Gas Chromatography/Mass Spectrometry GC/MS as a complementary technique can address volatile PFAS compounds that are challenging to be analyzed by LC/MS. 

In this webinar, a Head-Space Solid Phase Microextraction-Triple Quadrupole Gas Chromatography/Mass Spectrometry (HS-SPME GC/MS/MS) analytical method is used to analyze volatile PFAS in water. In addition, we will discuss Adsorbable Organic Fluoride (AOF) analysis by Combustion Ion Chromatography (CIC). This method provides information on the total amount of PFAS that may not be targeted by other selective chromatography methods.

We will host a Q&A session after the presentation to address any questions or comments.
