Mass spectrometry (MS) is an analytical technique used to identify and quantify molecules based on their mass-to-charge ratio (m/z). It provides valuable information about the chemical composition, ...

Perhaps no tool has been as instrumental to the proteomics revolution as the mass spectrometer. With the ability to deconvolute highly complex mixtures over a wide range of abundance levels, these ...

The mass spectrometer is an instrument which can measure the masses and relative concentrations of atoms and molecules. It makes use of the basic magnetic force on a moving charged particle. It ...

Mass spectrometry is already a powerful tool for determining what kind and how many molecules are present in a given sample. But most instruments still analyze their molecules one or just a few at a ...

In Star Trek, Mr. Spock’s hand-held tricorder can instantly tell what something is made of. We don’t have tricorders yet, but we’re getting close. Portable devices just a little too big to hold in one ...

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, ...

Mass spectrometry is a powerful analytical method used to identify and characterize molecules. People often mistakenly think that the data outputted by the technique come in the form of a mass ...

Day 1 of the annual meeting of the American Society for Mass Spectrometry (ASMS; NM, USA) has been jam-packed with press conferences from the biggest names in mass spectrometry, and I have been to ...

Just how far mass spectrometry—the use of tools measuring the mass-to-charge ratio (m/z) of one or more molecules present in a sample—has progressed over the past century can be seen in a new exhibit ...

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 ...
