The ability to measure mass to charge ratio of the ions in mass spectrum is the most important feature of the high-resolution mass spectrometers. An analyte's identification can be progressed further ...

In mass spectrometry, a sample is analyzed to determine its molecular composition through the generation of a spectrum that reveals the masses of its component parts. A transfer line introduces the ...

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, ...

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 ...

After three years of development, the National Institute of Standards and Technology (NIST) has released a major upgrade of the widely used NIST/EPA/NIH Mass Spectral Library. The library is an ...

Most biomolecules are chiral. Circular dichroism (CD) spectroscopy is typically used to provide information about that chirality. But the data for mixtures of biomolecules can be difficult to ...

At the University of Oxford, Justin Benesch studies assemblies made between proteins called molecular chaperones and the proteins they protect in cells. These assemblies slow the formation of amyloid ...

The process of protein identification typically begins with a bottom-up approach, where proteins are enzymatically digested—most commonly with trypsin—into smaller peptides. These peptides are ...
