Corrosion

Electrochemical noise has become popular as a new method of corrosion detection and prevention. ZAHNER has developed the CorrElNoise® technique, the first method to obtain both, potential noise and current noise from one electrochemical source.

CIMPS

The ZAHNER CIMPS system based on LED arrays brings an additional advantage compared to the IMPS described in the literature: a control loop regulates light intensity and modulation and keeps it absolutely stable.

The automatic comparison between set value and sensed intensity eliminates the influence of non-linearity, ageing and temperature drift. Furthermore, it allows the direct calibration of the light source in units of intensity (W/m²).

The CIMPS package consists of several components, working together in a plug & play application, including software and an overall calibration of the system. An ZENNIUM X/pro or ZENNIUM electrochemical workstation acts as a frequency response analyser and as a control unit (potentiostat / galvanostat) for the cell under test. All ZENNIUM series workstations are renowned for their high precision, ease of use and comprehensive software. A slave potentiostat, driven by the ZENNIUM system, controls the amplitude and the modulation of the light source over a wide range of frequencies.

An optical bench carries the housing of the light source with the integrated photo-amplifier and the slider with the photo-electrochemical cell PECC-1 or PECC-2. The PECCs are a versatile option completing your CIMPS setup for performing photoelectrochemistry in solution. A photodiode sensor, included in the CIMPS setup, is mounted near the site of the light inlet of your obejct (solar cell, PECC, etc.), adjustable in height and angle. Depending on the application, you can chose from different types of light sources, which are optional components making your CIMPS system an highly flexible tool for your photoelectrochemical research.
