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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

Mass spectrometry is a powerful analytical method used to identify and characterize molecules. People often mistakenly think that the data outputted by the technique come in the form of a mass ...

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 ...

In mass spectrometry (MS), workflows are being streamlined and analyses are becoming more sophisticated. In short, MS is becoming faster, easier to use, and more functional. This is welcome news for ...
