Long Title: IUPAC Gold Book - change of mass

Status: current

Definition
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.
