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 crucial role in preventing future terrorist attacks on airplanes and 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 luggage and on passengers.
R. Graham Cooks, the leader of the research team, has spent years advancing mass spectrometry, a powerful analytical technique that identifies the molecular composition of substances with high accuracy. However, traditional mass spectrometers are not practical for use in airports due to their size, complexity, and the need for liquid samples.
Cooks and his team have taken this technology to the next level by developing a new method that uses a stream of air instead of liquid samples. This allows the device to "sniff out" trace amounts of hazardous materials from a bag or even a person’s clothing. The system is fast, efficient, and highly sensitive, providing results in just 3 to 5 seconds.
Weighing around 25 pounds, the device is compact and portable, making it ideal for deployment in airports, security checkpoints, or even on aircraft. Its ability to quickly identify dangerous substances could significantly enhance aviation security and help prevent potential threats before they escalate. By streamlining the screening process, this innovation not only improves safety but also reduces the stress and inconvenience experienced by travelers during security checks.
