Abstract: An extraction cartridge, for extracting a component from a composition, contains a packing composition including a buffer composition, diatomaceous earth and absorbent. The cartridge is made by heating each component to assure it is free from contaminants. The diatomaceous earth is sifted to obtain a particular particle size. The cartridge also includes frits and filters for holding the packing composition within the cartridge. All of the components of the cartridge are selected or processed to assure that no contaminants are leached into the sample being extracted. A processing system automatically processes a plurality of cartridges. The processing system, which is capable of continuous operation, includes a platform, a rack for holding the cartridges, sample vials and extraction tubes.
