Diatomaceous earth products
Hydromatrix™ and Chem Elut™: Supported Liquid/Liquid Extraction
• High purity sorbent eliminates contamination and leachables • Available in pre-packed or bulk formats for flexibility • Packing method delivers excellent tube to tube and well to well reproducibility Hydromatrix is a high purity, inert diatomaceous earth sorbent available in 96-well plate formats and also as bulk material, offering end user flexibility and an excellent diversity of applications. Chem Elut products contain Hydromatrix loose material in convenient, ready to use cartridges. Chem Elut is an economical broad performance sorbent for rapid, general sample preparation of biological samples such as plasma, serum, whole blood and urine. Chem Elut products are available in buffered and unbuffered formats. The buffered devices can be used for simple scrubbing operations on organic reactions. The acid buffered cartridge effectively removes excess amines from a synthetic transformation, while the base-treated cartridge can remove residual acid compounds from a variety of matrices.
