Advantages • Increase in productivity or sample throughput from unattended operation. • Solid-phase extraction technology to save labor time and solvent. • Decrease sample analysis costs through savings of labor and solvents. Extremely Large Volume Liquid-Liquid Extractions The most often is Silica-Based SPE Cartridges, also can choose different packing according to extraction condition(pH, polar of compounds). Bonded silica gel based: ODS, C8 COOH, Silica, PSA, PRS, SCX, SAX Diol high molecular polymer based: PEP, HXN, PS, PAX, PCX Adsorbability material based: Florisil, PestiCarb, Alumina-N,...
