Photoionization mass spectrometry has transformed analytical chemistry, enabling complex chemical analysis and celebrating a ...

In mass spectrometry, a sample is analyzed to determine its molecular composition through the generation of a spectrum that reveals the masses of its component parts. A transfer line introduces the ...

Effective protein characterization depends on the precise isolation and fragmentation of peptide ions within the mass spectrometer, typically coupled with liquid chromatography (LC-MS/MS). In a ...

Researchers 3D printed a mini quadrupole mass filter, a key component of a mass spectrometer, that performs as well as some commercial-grade devices. It can be fabricated in hours for a few dollars ...

Beijing Zhongke Journal Publising Co. Ltd. The traditional method for detecting dissolved gases in the deep sea is offline detection, which combines pressure sampling with laboratory analysis. This ...

When ion mobility spectrometry (IMS) and mass spectrometry (MS) were first combined in a commercial instrument more than a decade ago, users had limited options. If they wanted the analytical power ...

For biologists, seeing is believing. But sometimes biologists have a hard time seeing. One particularly vexing challenge is seeing all the molecules in an intact tissue sample, down to the level of ...

The utilization of online process analytical technology (PAT) has become a high-profile endeavor in the biotechnology industry in recent years. Since the early 1980s, many fermentation scientists have ...

NASA has funded Southwest Research Institute’s Environmental Analysis of the Bounded Lunar Exosphere (ENABLE) project, which aims to return mass spectrometry to the lunar surface. The three-year, ...
