Chem Elut and Tox Elut are economical Supported Liquid Extraction choices, available in buffered and unbuffered configurations. Agilent SLE products use a broad-performance inert diatomaceous earth sorbent for rapid, general sample preparation. Clean, inert diatomaceous earth sorbent material provides a surface for the aqueous sample, and an immiscible solvent is used to perform the extraction, resulting in a clean extract. Chem Elut Plus uses a diatomaceous earth sorbent that is specially prepared for trace-level analysis. SLE offers advantages over standard liquid-liquid extraction methods, including support for automation for high throughput, and better recoveries and precision by removing issues with emulsions that are often formed when performing liquid-liquid extraction.
