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 ...

In 2009 researchers found an "ionization surprise" that defied explanation. Until that time, it had been commonly thought that the ionization of atoms by strong laser fields was well-understood, but ...

What are the ionization techniques for mass spectrometry? Mass spectrometry (MS) plays a vital role in many aspects of our lives, from diagnosing illness and detecting food contaminants to fighting ...

Researchers have for the first time measured the first ionization energy of lawrencium, the last of the actinides, validating predictions of the element’s electronic structure (Nature 2015, DOI: ...

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 ...

This report both complements and extends Technical Reports Series No. 277/2, Absorbed Dose Determination in Photon and Electron Beams - An International Code of Practice, IAEA Technical Reports Series ...
