In preliminary work, it is found that the sensitivity achieved using a miniature mass spectrometer with a discontinuous atmospheric pressure interface (DAPI) is comparable with those achieved using ...

Researchers are designing new ways to make spectrometers that are ultra-small but still very powerful, to be used for anything from detecting disease to observing stars in distant galaxies.

For electrical engineers working in almost any part of the wired or wireless spectrum, the spectrum analyzer is a critical test and measurement tool. For optical engineering, the equivalent tool is ...

Researchers at the University of Lille developed a device (right) called the SpiderMass that can ionize lipids, metabolites and proteins at atmospheric pressure, remote from the mass spectrometer.

In this article, we discuss the principle behind the functioning of glow discharge optical emission spectrometry, some of its practical applications as well as studies that have used the technology in ...
