Recently, mass spectrometry methods have been developed ... resistance that is mediated by gene mutations, mobile genetic elements or virulence factors. In general, methods based on the detection ...

A key element to all mass spectrometry (MS) systems is the type of detector used to convert a current of mass separated ions into measurable signal. Different types of detectors are used depending ...

In a stunning new discovery, researchers at the University of Jyväskylä, Finland, have uncovered a mysterious “bump” in the nuclear binding energies of lanthanum isotopes. This unexpected feature is ...

When photons of light pass through a gas, the photons with the same energy as the energy gaps in the atoms can be absorbed. This causes an absorption spectra, as shown below. Because the energy ...

After air-drying for 45 min, the sections were dried for 2 h in a desiccator before mass spectrometric analysis. This application technique results in formation of crystals of the organic matrix ...

Studying the line spectra produced by hot gases and absorbed by cooler gases allows us to identify the elements in stars. When a gas is very hot, it doesn’t emit all wavelengths of light.
