The United States developed a new mass spectrometer to effectively detect dangerous substances
A groundbreaking mass spectrometry technology developed by researchers at Purdue University in the United States could play a key role in preventing future terrorist attacks on aircraft and significantly reducing passenger anxiety.
Located in the basement of the Wetherill Chemical Laboratory, a team of scientists has created an innovative system capable of detecting explosives and chemical residues in passenger luggage. The project is led by R. Graham Cooks, a pioneer in mass spectrometry, a technique that identifies the molecular composition of substances with remarkable accuracy. However, traditional mass spectrometry methods are not practical for use in airport security due to their size, complexity, and time requirements.
Cooks and his team have taken this technology to a new level by developing a novel approach that uses a stream of air rather than liquid samples. This allows the device to "sniff" out trace amounts of hazardous materials from both bags and individuals, making it much more efficient and versatile.
The system can analyze a sample in just 3 to 5 seconds, providing rapid and reliable results. Weighing approximately 25 pounds, the device is compact and portable, making it ideal for deployment in airports or other high-security environments. By enabling quick and accurate detection of dangerous substances, this technology has the potential to enhance aviation safety and prevent potential threats before they become a reality. Its development marks a significant step forward in the ongoing effort to protect travelers while minimizing disruption during security screenings.
