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 ...
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 ...
During the analysis of NH 3 in H 2 O gas streams, a big issue when trying to detect low NH 3 levels arises due to the spectral overlap between the m/z 17 of both NH 3 and water. The water background ...
