Real-time analysis

Would you prefer to concentrate on science rather than measurement technology?

The Spectro Inlets EC-MS is the first and only turnkey solution for mass spectrometry analysis of electrochemical reactions.

Ready to perform out of the box, the system is controlled by powerful software allowing the control of the potentiostat, mass spectrometer, gas, and vacuum systems from a single integrated graphical user interface.

Unparalleled time response

Measure composition changes of volatile species with a time resolution down to 0.1 seconds

Exceptional sensitivity

Measure submonolayer desorption phenomena with sub-second time resolution and easily record transient effects.

Fully integrated software

Control instrument and measurements from an integrated, user-friendly graphical user interface.

Unparalleled electrochemistry studies

The Spectro Inlets analysis system is a complete platform for electrochemistry experiments with real-time measurements.

It incorporates our unique microchip inlet technology with a vacuum and gas-handling system and a mass spectrometer to deliver unprecedented real-time measurements of volatile substances in liquid environments.

As a result, the EC-MS can characterize minute gas evolution at the surface of an electrode for electrochemistry and battery R&D.
