Aid for the Medical Laboratory

A process for separating chemical compounds in fluids resulted from a Jet Propulsion Laboratory (JPL)/LAPD project. The technique involves pouring a blood or urine sample into an extraction tube where packing material contained in a disposable tube called an extraction column" absorbs water and spreads the specimen as a thin film making it easy to identify specific components. When a solvent passes through the packing material the desired compound dissolves and exits through the tube's bottom stem and is collected. Called AUDRI Automated Drug Identification it is commercially produced by Analytichem International which has successfully advanced the original technology."
