SPELEC RAMAN
Description
Metrohm Autolab
SPELEC RAMAN is an instrument for performing spectroelectrochemical RAMAN measurements. It combines in only one box a LASER Class 3B (785 nm), a Bipotentiostat/Galvanostat and a spectrometer (wavelength range 785 – 1010 nm and Raman shift 0-2850 cm-1) and includes a dedicated spectroelectrochemical software that allows optical and electrochemical experiments synchronization.
