Presentations
Efficiency in EPA Method 1633: Validation and Implementation Strategies
by Jeffrey Smith, Director of Operations, Complete Environmental Testing (CET)
This presentation focuses on optimizing EPA Method 1633 in your laboratory highlighting the validation and implementation of dual-phase WAX and GCB cartridges. EPA 1633 establishes a method for the determination of 40 PFAS from challenging matrices such as non-potable waters, soils, biosolids, and tissue. For these matrix types, sample preparation has moved beyond the use of a WAX cartridge alone. GCB has been added to the sample preparation workflow to provide additional sample cleanup. We discuss the full EPA 1633 workflow, including topics such as background analysis for soils and water, MDLs achieved, observed recovery in authentic samples, and the practical advantages of dual-phase cartridges in reducing manual labor steps compared to loose GCB in EPA 1633.
This presentation is designed for scientists, laboratory managers, and others looking to implement and validate EPA Method 1633 or optimize their sample preparation process in their current workflow. Listen as Complete Environmental Testing shares experiences on working with the complex matrices in EPA 1633 and breaks down advantages in their method workflow with the use of dual-phase SPE cartridges.
Untapped Ultrashort-chain PFAS Analysis Combined with Routine PFAS Analysis in a Single LC-MS/MS Run
by Mike Chang, Market Development Manager, Restek Corporation
Starting from measuring C8 many decades ago, today’s PFAS testing requires a lot more chromatography capabilities when an extended list of PFAS analysis is desired. Chain length ranging from C1 to C18 and a functional group changing from carboxylic acids to ethers, sulfonamides, and more, with multiple oxygens in the structure, can be challenging for a chromatograph all in one run. In this presentation, we see examples of a combined PFAS panel analyzed in one run with chain length from C1 and above, in addition to AFFF and FTS compounds.
