UV-vis-NIR Spectroscopy

Jasco V-670 double beam UV-vis-NIR-Spectrometer (190-3200 nm)
Spectroelectrochemistry

Princeton Applied Research Potentiostat PAR 283

Spectroelectrochemical experiments in reflexion were performed in our Jasco V-670 Spectrometer in combination with a specially designed sample compartment consisting of a cylindrical quartz cell, a platinum disc electrode (6 mm), a gold-covered metal (V2A) plate as the counter electrode and a Ag/AgCl pseudo-reference electrode.

Spectroelectrochemical measurements in transmission were performend in a quartz cell containing a minigrid-goldnet as the optical transparent working elektrode.
