Description
Book SynopsisCovering the developments in sensor technology and electronic sensing devices, this book provides aid for those wishing to use chemical and biosensors. It covers key features and subjects that include: sensors based on both electrochemical and photometric transducers; mass-sensitive sensors; thermal-sensitive sensors; and more.
Trade Review"...It would be a valuable addition to university libraries..." (Chemistry in Britain, November 2002)
"...a useful contribution to introducing the subject to a wider range of analytical scientists..." (Chemistry & Industry, 3 March 2003)
“…covers a wide range of sensoring systems…accessible to a broad audience.” (Metrohm Information, Vol.33, No.2 2004)
