SPE与大体积进样技术在EPA8270方法上的应用实例

Automated solid-phase extraction in combination with large-volume injection techniques provide environmental laboratories with methods that completely eliminate the postextraction reconcentration step normally required for the analysis of semivolatile compounds. Elimination of this step and automating the SPE sample preparation procedure reduce analyst labour, solvent usage, and turnaround time, and improve accuracy and precision.
