New theory addresses frozen Earth paradox
WEST LAFAYETTE, Ind., Aug. 23 (UPI) -- U.S. researchers say they've developed a shoebox-sized, handheld mass spectrometer to be used to prevent potential terrorism incidents.
The instrument, produced by R. Graham Cooks, Zheng Ouyang and colleagues at Purdue University, is capable of detecting minute amounts of chemical compounds in the environment. Among the toxic and dangerous chemicals the instrument can detect are the peroxides believed involved in alleged plans to blow up British passenger jets.
The long-sought, portable mass spectrometer named the Mini 10 weighs 22 pounds, some 30 times less than a conventional mass spectrometer. The new unit uses about as much battery power as a laptop computer.
The instrument will be fully described in the Sept. 15 issue of the journal Analytical Chemistry.
