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 ...

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 ...

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: ...

Aerospace giant Boeing tested two kinds of ionization technologies — like those widely adopted in schools hoping to combat Covid-19 — to determine how well each killed germs on surfaces and decided ...

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 ...

Ever been up in the mountains, at the beach, or in a thunderstorm and suddenly felt a huge change in your mood? That’s not just a feeling of awe. It might be negative ions. Negative ions are molecules ...

In his paper, "Flash Ionization of the Early Universe by Pop III.1 Supermassive Stars," published on the arXiv preprint server and forthcoming in The Astrophysical Journal Letters, Tan, who is also a ...
