A new mass spectrometry technique captures molecules of lower abundance in a sample, providing a more comprehensive sample ...

Sample preparation for mass spectrometry has been the topic of several recent symposia extensively covered in the pages of GEN. Mass spectrometry has grown over the years into an essential tool for ...

This EA-IRMS system can simultaneously measure δ 13 C and δ 15 N of bulk organic material, as well as quantify %-Carbon and %-Nitrogen of the sample. Potential samples include sediments, plant tissues ...

Gas chromatography is used to separate the components of a sample and provide a spectral signature for it. The procedure involves injecting the sample into the injection port of the gas chromatography ...

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 ...

Immunopeptidomics is a cutting-edge field focused on identifying and characterizing peptides presented by major histocompatibility complex (MHC) Class I and II molecules on cell surfaces. These ...

In quality control and chemistry, analytical samples are usually mixtures. Understanding the main compound’s assay and the number of impurities or other unwanted substances in the sample is essential ...

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 ...

While many people often use spectroscopy and spectrometry interchangeably, there are some subtle differences in their exact meanings and the associated experimental techniques they are used to ...

Velaris has acquired Markes International from Schauenburg International, strengthening its automated sample preparation portfolio, expanding its global presence, and enhancing support for ...
