In the basement of the Wetherill Chemical Laboratory, a team of researchers developed a new technology that detects the presence of explosives and chemical residues in passenger luggage. Research team leader R. Graham Cooks has long been working on mass spectrometry. Mass spectrometry is able to determine the composition of a particular compound and is highly reliable. But the usual mass spectrum cannot be used on the aircraft.
Researcher Cooks takes this technology to the next level: his research team invented a new process that uses a stream of air instead of a liquid sample and can "sniff" any residue in a bag or a person.
This machine takes only 3 to 5 seconds to determine the presence of hazardous residues and hazardous materials. The instrument is small and portable and weighs about 25 pounds. This new technology makes it quick and easy to detect the presence of dangerous objects on the aircraft and may increase the safety of the aircraft and prevent terrorist attacks.
The United States developed a new mass spectrometer to effectively detect dangerous substances
A new mass spectrometry technology developed by Purdue University in the United States may help prevent future terrorist attacks on aircraft and ease passenger stress.
