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 ...

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 ...

Not all smoke detectors are equal, and the type of smoke detector installed in many homes might not sound off in all fires. Smoke alarm manufacturers sell alarms with two types of technology.

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 ...

An air ionizer releases negative ions into the air. This helps particles clump together and land on a surface, which could be cleaned. Benefits include mold, bacteria, and virus prevention, among ...
