...Doping Control Center of the Korea Advanced Institute of Science and Technology, it took twelve hours more to assay the day's samples, to run them through the mazy innards of the lab's instruments. When the last sample left the hair-thin glass tubes of the gas chromatograph and the mass spectrometer, where all molecules have their fingerprints taken, just one positive result had turned...
...basic test has been employed before, but it has been refined with new computer software. The gas chromatograph mass spectrometer utilized in Caracas is capable of detecting substances in concentrations as small as one part per billion and can pick up traces of compounds taken as much as six months earlier. Ten Americans had requested private pretesting at Caracas, and even though eight of them showed traces of drugs, they competed and risked the official test. Oddly enough, Michels passed the first, confidential screening, reportedly because it was not as complete as the urinalysis conducted later. Michels reportedly told fellow...
...always perform as promised. The reliability of some supposed wonders, including lie detectors, voice-print machines and hypnosis, are so in doubt that many courts will not hear the resulting evidence. But more, not less, scientific evidence is likely in the future. With the help of an ion chromatograph, FBI technicians are starting to determine not only the type but even the manufacturer of explosive substances. Lasers are enabling experts to lift fingerprints from difficult surfaces like cloth and even the human body. Kansas City's Howell believes that the coming years will see a great increase...
...least 50 milliliters (less than 2 oz.) of urine will be collected. The sample will be sent to the laboratory in two bottles: one will be stored in a sealed box in a refrigerator; the other specimen will be analyzed immediately. The urine will be placed in the gas chromatograph, which separates out constituent elements one by one. For example, amphetamines come out in three minutes, narcotics and steroids in about 20 minutes. Their presence is signaled by a "spike" in a pengraph tracing made by the machine. No spike, no drugs...
