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 electrochemical workstation IM6 or Zennium acts as a frequency response analyser and as a support unit (potentiostat / galvanostat) for the cell under test. The IM-series workstations are renowned for their high precision, ease of use and comprehensive software. A slave potentiostat, driven by the IM6/Zennium system, controls amplitude and 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 slide with the photo-electrochemical cell (PECC-1 and PECC-2). A photodiode sensor is mounted near the site of the cell’s light inlet, adjustable in height and angle. Depending on the application, you can chose from different types of light sources.
