The history of EC-MS and DEMS
Traces the evolution of electrochemistry–mass spectrometry from Hoch and Kok’s 1963 introduction of membrane inlet mass spectrometry (MIMS) through key DEMS milestones – Bruckenstein and Gadde’s PTFE membrane (1971), Baltruschat’s stagnant thin-layer cell (1993), and Jusys et al.’s dual thin-layer flow cell (1999) – up to Spectro Inlets’ chip-based EC-MS, which offers 100% collection efficiency and sub-second time resolution without differential pumping.
About EC-MS Technology
Explains the membrane-chip technology behind Spectro Inlets’ EC-MS systems: a 100 µm thin-layer cell couples the electrolyte directly to mass-spec vacuum without differential pumping, giving 100% collection efficiency and true quantitative detection. Covers key specs – 0.1 s time resolution, sensitivity to 10 ppm of monolayer desorption, a 7-order-of-magnitude dynamic range – plus on-chip gas dosing and synchronized EC-Lab data acquisition.
