Chemical sensors are integral to the automation of myriad industrial processes, as well as everyday monitoring of such activities as public safety, engine performance, medical therapeutics, and many more. This massive reference work will cover all major categories of chemical sensor materials and devices, and their general functional usage...from monitoring and analyzing gases, to analyzing liquids and compounds of all kinds. This is THE reference work on sensors used for chemical detection and analysis. In this fifth volume will be found comprehensive coverage on electrochemical gas sensors, zirconia-based solid electrolyte based gas sensors, electrochemical sensors for liquid environments, micro-fluidic chip platforms, optical- and fiber-optical sensor technologies, and new developments in chemoluminescence chemical sensors.
