UV-VIS-NIR Spectroelectrochemistry with Metrohm Autolab

Advanced real-time analysis of redox processes, reaction mechanisms, and material transformations with Metrohm Autolab’s EC–UV-VIS-NIR solutions

Metrohm Autolab offers a complete UV-VIS-NIR spectroscopy setup, as well as electrochemical instruments with full flexibility in the choice of potentiostat — all controlled by the powerful NOVA software package.

Versatility, Flexibility and Ease of use

• Unified Control: Electrochemical and spectroscopic components managed via one powerful software platform (NOVA)
• Optimized Measurement :
  • Automatic and manual shutter control
  • Flexible and programmable methods
  • Selectable integration time
• Accurate Synchronization: Electrochemical signals and UV-VIS-NIR spectra
• Advanced Analysis:
  • Dark and blank spectrum subtraction
  • Absorbance and transmittance calculations
• Outstanding local Metrohm support for configuring, using, and troubleshooting the complete hyphenated solution

Supports Standard UV-VIS-NIR Spectroelectrochemistry Workflows

• Dark spectrum collection with the light off
• Reference spectrum collection in supporting electrolyte with light on
• Electrochemical measurement (i.e. CV, LSV or Chrono) with spectra collected at user-defined intervals
• Data is collected and represented as overlay of absorbance or transmittance spectra and electrochemical signal in 2D or 3D plots
• The changes in the spectra as a function of electrochemical environment can be analyzed in NOVA software

The Metrohm Autolab Spectrophotometer is a compact device for applications in the UV-VIS-NIR wavelength range (200 - 1100 nm). This instrument is designed to work in combination with the Metrohm Autolab potentiostat/galvanostat controlled by the NOVA software. The spectrophotometer can be synchronized with electrochemical measurements, enabling direct and accurate correlation between electrochemical and spectroscopic data.

Explore our electrochemical workstations — from modular systems to compact benchtop models — which are compatible with the Metrohm Autolab UV-VIS-NIR spectrometer and light source. The control of the potentiostat, spectrometer, and light source, as well as parameter settings and data acquisition for both electrochemical and optical measurements, are all handled within the powerful NOVA software.
