Solid Phase Extraction(SPE) Systems are advanced instruments developed by integrating liquid-solid extraction and liquid chromatography technologies. They utilize solid adsorbents to adsorb target compounds from liquid samples, separating them from matrix and interfering compounds. Target compounds are then eluted with eluents or desorbed by heating, achieving the purposes of separation, purification, and enrichment. These processes reduce matrix interference and enhance detection sensitivity. The systems are applied in food safety testing, agricultural residue monitoring, pharmaceutical & healthcare, environmental protection, commodity inspection, tap water analysis, and chemical production laboratories.
