Tandem mass spectrometry is a powerful tool in proteomics. By ionizing peptides and then fragmenting those ions into smaller product ions, researchers can determine the biomolecules’ amino acid ...

Waters’ newest tandem quadrupole mass spectrometer is up to 15X more sensitive for analyzing negatively ionized compounds Xevo TQ Absolute is up to 45% smaller, uses up to 50% less power and nitrogen, ...

Mass spectrometry has emerged as an indispensable tool for the structural elucidation of oligosaccharides, offering unrivalled sensitivity and precision in the analysis of complex carbohydrate ...

The sample throughput of high-sensitivity liquid chromatography-mass spectrometry (LC-MS) based proteomics analysis is restricted by the pressure limitations of LC and column hardware, with some ...

Clinical applications for mass spectrometry technology have exploded in recent years. Mass spectrometry analysis is often faster, cheaper, and more sensitive than other methods and is thus ideally ...

When researchers perform peptide mass fingerprinting on gel slices, they typically use matrix-assisted laser desorption/ionization time-of-flight (MALDI-TOF) spectrometers, such as Applied Biosystems' ...

Last summer got off to a hot start at the June 2005 American Society for Mass Spectrometry meeting in San Antonio, Texas. With new product releases ranging from labeling reagents for quantitative ...

There’s more to RNA analysis than determining nucleotide sequences. There’s also the detection of post-transcriptional modifications (PTxMs). More than 170 PTxMs are known, and they seem to affect ...
