Chemcal bomb sensor
WebThe sensors are based on mass spectrometry, a technique able to analyse minute chemical samples, in this case the target chemicals at one part per quadrillion, or a thousand million! Project modelling indicates that a mobile network would require fewer sensors than a stationary network, and that 4-5 mobile sensors per city should suffice. WebA bomb calorimeter is used to measure the heat created by a sample burned under an oxygen atmosphere in a closed vessel (bomb), which is sur-rounded by water, under controlled conditions. The measurement result is called the Combustion-, Calorific- or BTU-value. (BTU-value is more common in the U.S.A.) Note: The term “bomb”
