Optimizing the Preconcentration of Volatile PFAS Precursors - A Comparative Study of SPME Geometries

Optimizing the Preconcentration of Volatile PFAS Precursors - A Comparative Study of SPME Geometries

This Application Note summarizes a study by Williams et al. (2025) that performs a comprehensive comparison of two Solid Phase Microextraction (SPME) geometries: the traditional SPME Fiber and the robust SPME Arrow. The study systematically evaluates the impact of SPME geometry and extraction mode (Headspace vs. Direct Immersion) on extraction efficiency. The results provide a clear, data-driven basis for method development, showing how SPME configurations can be optimized for the specific physicochemical properties of different PFAS analytes.

PFAS in Cosmetics -A Comparative Analysis of Sample Preparation Techniques for PFAS Analysis

This application note explores a comparative study that tackles this challenge head-on by evaluating two powerful sample preparation techniques: Solid Phase Microextraction (SPME) and Micro Solid Phase Extraction (µSPE) for analyzing eight key PFAS in mascara by Liquid Chromatography with Mass Spectrometry (LC/MS). The investigation revealed that the two methods offer complementary strengths. SPME proved more sensitive for water-soluble PFAS and offered a simpler, filtration-free workflow. In contrast, automated µSPE excelled for oil-soluble PFAS but required a sample filtration step.

Automated SPME-SICRIT-MS for Rapid Screening of Contaminants in Food and Environmental Matrices

Ambient mass spectrometry offers a path to rapid, direct analysis with minimal sample preparation. This note describes a high-throughput workflow for the analysis of both polar and non-polar analytes by coupling automated Solid Phase Microextraction (SPME) with soft ionization by chemical reaction in transfer (SICRIT), a variant of dielectric barrier discharge ionization (DBDI).
Using a PAL RTC autosampler, this workflow enables the rapid screening of contaminants in various water, soil, and food matrices.

ASMS 2025 - Fully automated implementation of EPA Method 1633 for LC-MS/MS analysis of PFAS in environmental samples using a customized robotic autosampler

Widespread use and persistence of PFAS has led to ubiquitous detection in water, soil, air, and living organisms.
US EPA Method 1633 is intended for analysis of PFAS in aqueous, solid and tissue samples using LCMS/ MS at part-per-trillion concentrations.
This method involves significant sample preparation and purification steps prior to instrumental analysis, leading to bottlenecks in sample processing.
We have developed a fully automated, online μSPE-LC-MS/MS workflow based on a customized LC TriPlus RSH SMART Advanced system for high-throughput analysis of PFAS in environmental samples following EPA Method 1633 guidelines
