Real-time monitoring of the degradation of Cu(II)-EDTA in H2O2/UV using illumination-assisted droplet spray ionization mass spectrometry

Illumination-assisted droplet spray ionization (IA-DSI) mass spectrometry was developed for in situ analysis and real-time monitoring of photolysis reactions. In IA-DSI, a photolysis reaction occurs on a corner of a cover slip positioned in front of a mass spectrometer, and the generated reaction intermediates are ionized via the corner and are directed to the inlet and analyzed by a mass spectrometer. IA-DSI is contaminant-free, low-cost and...
