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&quot; 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&apos;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.&quot;
