NOVOCONTROL
Active Sample Cell ZGS
The accurate characterisation of elec­
trical properties of materials over thewidest ranges of impedance and fre­quency not only requires an appropria­
te impedance analyzer, but also a
suitable sample cell that allows easy
and reproducible sample mounting,appropriate electrical insulation of thesample electrodes and perfectconnection to the temperature control
environment. The Novocontrol passive
sample cell ZGS combines all these fea­tures.

Methods• Electrical characterisation ofmaterials (solids/liquids/powder)in parallel­plate configuration• Electrical characterisation of liquids
on interdigitated electrodes• Dielectric Spectroscopy• Conductivity Spectroscopy• Electrochemical ImpedanceSpectroscopy
