Accurate determination of fluorine in organic materials is essential across a wide range of applications, including polymers, fuels, oils, and other complex chemical matrices. Fluorine-containing compounds can affect processing performance, product quality, and regulatory compliance, yet their reliable quantification remains challenging.

The determination of fluorine via a sum parameter is most commonly performed via combustion ion chromatography (CIC). Nevertheless, its detection workflow may restrict throughput and sensitivity in demanding organic matrices. These limitations have driven interest in alternative approaches that provide faster, more robust fluorine determination.

In this web seminar, we present a novel approach that combines sample combustion with high resolution continuum source molecular absorption spectrometry (HR-CS-MAS). The analytical workflow integrates a self-optimizing combustion system (ICprep) with a versatile graphite furnace spectrometer (contrAA 800 G), which also enables trace level determination of metals and metalloids using standard atomic absorption spectrometry from sample volumes as low as 20 µL.

Analytical performance is shown to be comparable to CIC in terms of accuracy and detection limits, while offering a substantial increase in throughput. Post-combustion analysis times of only three to four minutes per replicate allow more measurements per sample, improving statistical confidence, making the method well suited for routine and research level analysis of diverse organic matrices.
