Why an EC-MS from Spectro Inlets?

“The extremely high sensitivity will allow it to probe degradation processes that are significant over the calendar life of a battery, but which occur at a rate that is too slow to detect using the prior state-of-the-art. This will allow us to (i) understand what causes battery degradation (ii) predict with more accuracy the device lifetime of batteries, important for providing warranties for consumers (iii) develop processes that mitigate degradation.”

Why Spectro Inlets relative to alternatives?

“The unprecedented sensitivity (approximately 1000 times higher than the prior state-of-the-art), minimal electrolyte evaporation, highly quantitative output data and strong and attentive customer service.”

Dr. Ifan Stephens, Professor in Electrochemistry at Imperial College London

What insights can an EC-MS from Spectro Inlets give?

“We have beyond an original prototype set-up, two Spectroinlets systems in our laboratory. They are all used to give us unprecedented insight into electrochemical processes where different products are made.  For example, we have very recently used it to do isotope measurements and study the mechanism in detail that has not been possible earlier (see 12)  and to characterize entirely new catalysts on oxygen evolution catalysts (3). One machine is used for doing electrochemical CO2 and CO hydrogenation, and finally, we use one for analyzing the ammonia synthesis in non-aqueous electrolyte which is very challenging due to the presence of organic molecules and their decomposition products (4 & 5).”
