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.
PT Unitama Analitika Perkasa was established in 1997 and started operating in 1998.
