, HPLC, IC, MSPE). Critical validation parameters-including detection limits, recovery rates, precision, and enrichment factors-were systematically summarized alongside methodological characteristics such as typical separation media, key devices employed. Studies have shown that although some new pretreatment and detection technologies have emerged, hyphenated techniques still remain the mainstream in speciation analysis research. The review concludes with evidence-based recommendations for method selection guided by sample matrix characteristics and target speciation requirements while highlighting the imperative for continued innovation in achieving species-specific detection at environmentally relevant concentrations.
