A study suggests that gas chromatography-mass spectrometry modifies or destroys sample compounds, but some are skeptical.
Mass Spectrometry and Proteomics
Angelo DePalma | Aug 24, 2003 | 9 min read
Courtesy of Thermo Electron For years, mass spectrometry has been de rigeur in chemistry labs. Recently, though, it has become a mainstay of proteomics research, too. Two years ago, investment bank UBS Warburg identified proteomics as the fastest- growing application of mass spectrometry, a prediction borne out at this year's American Society for Mass Spectrometry (ASMS) annual meeting, where more than 1,100 of 2,227 presentations discussed some aspect of proteomics. It took a confluence of t

These elements would ultimately come to be known as isotopes, but at the time this concept was

Can Mass Spec Really Do That?
Jeffrey M. Perkel | Feb 1, 2010 | 7 min read
By Jeffrey M. Perkel Can Mass Spec Really Do That? Unexpected applications of a technique best known as a proteomics powerhouse. Mass spectrometry (MS) is not just about proteomics, though its star in that field certainly shines bright. As anyone in the drug discovery, food science, petroleum, or chemistry industries can tell you, mass spec is considerably broader than that. “Traditionally it was a technique for looking at relatively small compou
