change of mass

Detection principle for a chemically modified electrode (CME) in which the signal originates from accumulation and/or release of an analyte or reagent as well as other electrochemical processes which can result in changes in the mass of the CME.
Note: Simultaneous electrochemistry and microgravimetry can be accomplished by means of an electrochemical quartz crystal microbalance (EQCM, see electrochemical piezoelectric microgravimetry). For use with an EQCM, a CME is fabricated by covering one face of a metallized quartz resonator with a modifying film.
