Mass Spectrometry

Triple detection GPC/SEC combines measurements from multiple detectors to offer not only increased amounts of data, but also increased amounts of information, which is made available by the combination of different detectors (and unobtainable using individual detectors separately). The theory of triple detection GPC/SEC is described here.

This application note describes the analyses of a variety of aqueous (water-soluble) cellulose derivatives using the OMNISEC triple detection system and the subtle, yet distinct differences between these different derivatives that can be parsed out by the OMNISEC system

The investigative power of multiple detectors. Here, we describe the analysis of a semi-purified protein mixture containing β-amylase. Step-by-step, we show how different properties of the proteins elicit a specific response in each detector and how coupling this data can be qualitatively and quantitatively evaluated.

F. Scott Anderson, a staff scientist at the Southwest Research Institute, Boulder, Colorado, USA, discusses the potential of in-situ resonance ionization mass spectrometry for understanding the age of planetary bodies.

Scientists who are dissatisfied with the analysis of samples from our blue planet look to the stars

The seven seas represent an extremely challenging and almost boundless environment that a secret army of passionate oceanographers nevertheless joyfully dive into.

Multiplexed separations in metabolomics: is there a faster, cheaper, and better way?

A novel CE-MS technique shows great promise for sample-restricted metabolomics.

Researchers use SPME and GC-MS to puncture claims that banned tire treatments are “undetectable”
