ABOUT two years ago I noticed 1 that the positive ions generated along the path of an electron beam nearly all came out of the electron beam at right angles to it with energies of the order of 1 or 2 ...
The QTOF‐GCMS instrument integrates the excellent mass accuracy of the quadrupole time‐of‐flight (QTOF) mass spectrometer with the proven gas phase chromatography techniques. 1 Da (mass accuracy in ...
The study of ionisation cross sections and X‑ray production induced by electron impact forms a cornerstone in our understanding of atomic interactions and material characterisation. Ionisation cross ...
