Solid-phase extraction (SPE) is a sample preparation technique used to separate and concentrate specific compounds from a mixture by passing the sample through a solid adsorbent. This method enhances the monitoring and analysis of micropollutants by effectively isolating them from complex matrices like water, soil, or biological samples. SPE is crucial for accurate detection and quantification of these trace contaminants, ensuring better environmental assessments and regulatory compliance.
