Description

The Spectro Inlets analysis system 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. As the inlet is robust and self-cleaning,  the system is also suitable for monitoring dissolved gases for industrial applications such as biogas production and wastewater treatment.
