Metrohm Autolab

SPELEC NIR is an instrument for performing spectroelectrochemical measurements. It combines in only one box a Lightsource, a Bipotentiostat/Galvanostat and a Spectrometer (NIR wavelength range: 900-2200 nm) and includes a dedicated spectroelectrochemical software that allows optical and electrochemical experiments synchronization.
