Air‐free transfer from a glovebox
Standardize your EC-MS setup with reproducible benchmark measurements on Pt-Poly and glassy carbon electrodes. Covers cyclic voltammetry and chronopotentiometry procedures for HER and OER, plus M2 signal decay analysis to gauge system cleanliness and tuning status.
Potentiostat instability
EC-MS Technical Note #3: how capacitive EC-cells cause potentiostat instability in CV measurements, and how to fix it with a series resistor and post-measurement iR compensation.
Benchmark Measurements
EC-MS Technical Note #2: standardized cyclic voltammetry and chronopotentiometry benchmark measurements on Pt-Poly and GC electrodes, with expected M2 decay half-lives.
Gas Pulses
Learn how to send Ar and He gas pulses through the EC-MS gas exchange system with minimal switching time. Covers the step-by-step MFC and valve sequence, plus expected switching times — roughly 20 seconds from He to Ar, and 50 seconds from Ar to He.
