Copure® SLE

Supported Liquid Extraction (SLE) is a very efficient and economical sample preparation methodology. Extracting analytes from aqueous samples is achieved with a simple two-step protocol, i.e., loading and elution. In SLE, porous diatomaceous earth with high surface area and low chemical activity is packed as stationary support for liquid-liquid partition. While loading a sample, the aqueous sample solution passes through diatomaceous earth beads, allowed to adsorb via
