Item description: Hand-held mass spectrometer instantly detects drugs, explosives, chemical signs of disease.
Item uses new technology to detect ultra-tiny amounts of chemicals, explosives, pollutants, medicines, proteins, etc.
Product can separate chemicals for purification.
Item does analysis in seconds.
Item can process 10 samples/second!
No sample preparation! Instrument can analyze urine on paper or explosives on skin.
Mass spectrometry measures mass of charged particles (ions); is standard technique for detecting chemicals. Traditional mass-spec instruments are large, cumbersome, and slow. New instrument uses desorption electrospray ionization; sprays solvent at sample to release ions; instrument then sucks up ions. Item developed by R. Graham Cooks, Zheng Ouyang and Rob Noll at Chemistry Department, Purdue University, with funding from National Science Foundation.
Purdue University, West Lafayette, Ind., laboratory of R. Graham Cooks
