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.
ASMS 2025 - Streamlined Analysis of Polar and Non-Polar Metabolites in Plasma Using Automated Micro-SPE LC/MS
This poster presents two use cases for streamlined lipid profiling in plasma using automated Micro Solid Phase Extraction (μSPE). Where the workflows on NIST (SRM 1950) plasma samples was tested, with spiked internal standard (Ultimate SPLASH ONE) and optimized the extraction and elution parameters. Briefly, it focused on two cartridge sorbent types Mixed-Mode Cation Exchange (MCX) and C18 (CEC) and showcased their usage.
