Scientists from Russia and Germany studied the molecular composition of carbonaceous chondrites – the insoluble organic matter of the Murchison and Allende meteorites This was done in an attempt to ...

A research team led by Prof. Chen Chilai from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences has developed a deep-sea mass spectrometer. It has completed several sea ...

Mass spectrometry measures the mass-to-charge ratio of ions by ionizing chemical compounds to produce charged molecules. A typical mass spectrometer consists of three parts: a detector, a mass ...

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 ...

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 (MS) has long been a cornerstone of chemical and biological analysis, but in biotech and biomanufacturing, it is now experiencing a renaissance. As drug modalities diversify—peptides ...

Researchers developed a high-precision method to analyze PFAS carbon isotope ratios, supporting improved identification of ...

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 ...

Equipment for gas chromatography, liquid chromatography and mass spectrometry is complex, with multiple subsystems that control the flow of sample analyte, carrier gas and solvent fluids. The ...

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 ...
