SAW Sensor for Mercury Vapour Detection
Mercury is the element commonly applied in industry. Because of poisoning properties the monitoring of the mercury vapour concentration in the environment is very important. Mercury forms amalgams in connection with gold that causes a change in the electrical resistance and mass of the gold specimens. This e ect was applied to measure mercury vapour concentration in the environment using surfac...
متن کاملSelective detection of elemental mercury vapor using a surface acoustic wave (SAW) sensor.
The detection of elemental mercury (Hg(0)) within industrial processes is extremely important as it is the first major step in ensuring the efficient operation of implemented mercury removal technologies. In this study, a 131 MHz surface acoustic wave (SAW) delay line sensor with gold electrodes was tested towards Hg(0) vapor (24 to 365 ppbv) with/without the presence of ammonia (NH3) and humid...
متن کاملA miniaturised sensor for gaseous mercury detection
A new microfabricated physical sensor for elemental gaseous mercury (Hg) determinations has been developed and experimentally tested by the Authors. The sensor is based on the technique of resistivity variation of thin gold film. The gold film surface and the sensor behaviour on different substrates have been investigated. The sensor design has been performed in observation of the minimum detec...
متن کاملGraphene nanoelectronic heterodyne sensor for rapid and sensitive vapour detection.
Nearly all existing nanoelectronic sensors are based on charge detection, where molecular binding changes the charge density of the sensor and leads to sensing signal. However, intrinsically slow dynamics of interface-trapped charges and defect-mediated charge-transfer processes significantly limit those sensors' response to tens to hundreds of seconds, which has long been known as a bottleneck...
