Description
The Spectro Inlets analysis system is a complete platform to carry out electrochemistry experiments with real-time measurements. It incorporates our unique microchip inlet technology with a vacuum and gas-handling system in conjuction with a mass spectrometer to deliver unprecedented real-time measurements of volatile substances in liquid environments. The analysis system can characterize minute gas evolution at the surface of an electrode for electrochemistry and battery R&D.
