By analysing meteorites, Imperial researchers have uncovered the likely far-flung origin of Earth’s volatile chemicals, some of which form the building blocks of life. They found that around hal ...
Indoor air pollution is a serious problem in developing nations because of stoves, secondhand smoke, dust mites, mold, bacteria, cleaning products, and more. These sources release volatile compounds. The most studied indoor air pollutant is nitrogen dioxide (NO2).
In this application note, Markes demonstrates how thermal desorption with gas chromatography-mass spectrometry (TD–GC–MS) can be used to monitor the release of per- and polyfluoroalkyl substances (PFAS) during the application of aqueous filmforming foam (AFFF). The results of the study show that TD–GC–MS can be used to analyze target compounds and screen for non-target compounds, enabling researchers to gain a greater understanding of AFFF emissions.
Detection of taste and odor of chemical compounds was possible utilizing graphite carbon black laser desorption ionization mass spectroscopy.
