The ability to measure mass to charge ratio of the ions in mass spectrum is the most important feature of the high-resolution mass spectrometers. An analyte's identification can be progressed further ...

One of the main objectives and problems in the discovery of new secondary metabolites is the identification of an exact molecular formula for natural products. [1] Molecular formulas can be employed ...

The gaseous sample comprising of the VOCs to be examined (for instance, ambient air) is directly sampled into the PTR mass spectrometer without preparing any samples. The PTR ionization source is the ...

Researchers 3D printed a miniature ionizer, a key component of a mass spectrometer. Their device could someday enable an affordable, in-home mass spectrometer for health monitoring. Mass spectrometry, ...

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 ...
