With the INPHAZE Impedance Spectrometer you can measure the thickness and structure of:
- Surface Monolayers
- Bionic Interfaces
- Semiconductors
- Lipid Bilayers
- Membranes
- Polymer Films
Electrical impedance spectroscopy (EIS) applies a small, non-destructive, AC waveform to a sample and measures the subsequent attenuation and phase shift of the signal. The experiment is repeated over a range of frequencies and the results are modelled as a combination of resistors and capacitors which, in turn, are interpretted as the thickness and position of layers forming the surface, or interface, of the sample.
INPHAZE has innovative features, enabling it to achieve very high structural resolution at low frequencies.
Frequency Range 0.006 Hz to 1 MHz. Covers the range needed for nanotechnology and biotechnology applications.
Measurement range 0.1 to 1010 Ohms. The INPHAZE instrument is the only commercial spectrometer which can measure such an impedances range over the entire frequency spectrum.
Phase error 0.001°. The lower the error, the higher the precision. The INPHAZE spectrometer delivers higher phase resolution than any other commercial instrument, especially at low frequencies.
Magnitude error 0.002%. This is the ratio of the amplitudes of the voltage and current signals. The magnitude yields information on the electrical properties of the sample and, in conjunction with precise phase measurements, allows down to atomic scale resolution of the structure of layered materials.
INPHAZE system includes:
- High-precision Impedance Spectrometer
- Measuring Chamber (2–, 3– or 4–terminal) in Faraday cage
- Advanced software packages that control the spectrometer and interpret the impedance and phase data (including model optimisation routines for structural parameters, and a range of graphical output options).
