Portable Gas Detector Offers Simplified, Accurate Detection of Various Organic Compounds
In a groundbreaking development, researchers at Gdańsk University of Technology have developed a device called the "VOCs Analyzer" to analyze Volatile Organic Compounds (VOCs) in air samples. This device has been making waves in the medical field, as it offers a noninvasive method for doctors to investigate the exhaled breath of patients, signaling the need for a more detailed checkup.
The VOCs Analyzer, which will be published in the prestigious journal Review of Scientific Instruments on July 6, 2021, is a low-cost device of simplified maintenance and service. It consists of a gas chamber, a set of electrical valves, an electrical micropump, and a touch-screen electronic module for data processing and saving.
The device is currently being applied in hospital studies to determine the difference in the exhaled breath between healthy volunteers and patients infected by the COVID-19 virus. Sensor responses are recorded and can be parametrized for further data processing using various detection algorithms.
The VOCs Analyzer is capable of detecting and measuring the presence of VOCs within the span of 10 minutes. It uses commercial and prototype resistive gas sensors to detect VOCs such as methane, ethanol, toluene, methylene, nitrogen dioxide, formaldehyde, ammonia, among others.
In addition to its medical applications, the device can also monitor the air quality in a human environment, such as in an office or warehouse, to detect molds or bacteria by emitted smells. The device's ability to correct effects induced by temperature and humidity changes, thanks to additional environmental sensors, makes it a versatile tool for various settings.
The article, titled "Embedded gas sensing set-up for air samples analysis," is authored by Andrzej Kwiatkowski, Katarzyna Drozdowska, and Janusz Marek Smulko. The journal Review of Scientific Instruments, published by AIP Publishing, includes publications on instruments covering all areas of science, including physics, chemistry, materials science, and biology.
The project's publication in Review of Scientific Instruments signifies its significance in the scientific community. The article can be accessed at http://aip.scitation.org/doi/10.1063/5.0050445 after July 6, 2021. This innovative device is set to revolutionize the way we monitor and analyze air quality, offering a promising future in both medical and environmental applications.
