Automating mass spectrometry based glycan identification and quantitation using SimGlycan software

This webinar provides an introduction to SimGlycan software for high throughput glycan identification and quantitation. We show examples of the use of the software for LC-MS/MS workflows for 2-AB labelled glycans, processing data for quantitative workflows using the recently introduced Thermo Scientific™ Tandem Mass Tag™ Reagents. In an effort toward rapid profiling and identification of glycans, we have developed web based software modules to facilitate construction of custom databases.

Discovery OMICS and Progenesis QI for Food Authenticity Testing

For years, traders have been passing off a lesser quality rice as the world's finest long-grained, aromatic rice, basmati, in key markets like the US, Canada and the EU. Increased concern regarding the authenticity of basmati rice throughout the world have lead to new developments in Food Authenticity Testing.

Polymers found in seabirds’ stomachs: Comprehensive analysis applying FTIR and EDX technology

While polymers contribute to the convenience of modern life, they also threaten the environment and life, particularly in oceans, as plastic waste. Polymers decompose very slowly. Through physical impact they reduce in size and degrade into fragments of oxidized polymers. The effect of maritime animals or birds picking up polymer fragments of all sizes is well recognized all over the world. Especially fish are victims of human waste, but also seabirds, such as fulmars which carry plastic waste in their...

When the almost ubiquitous cell regulatory enzymes known as protein kinases go awry they can be involved in cardiovascular diseases, cancer and diabetes. The determination of the crystal structure of an important member of the family, PKGI (protein kinase GI) will have implications for understanding the biomolecular mechanisms and perhaps point the way to novel therapies. 

Fruiting bodies: Full metal mushroom

It is assumed that edible mushrooms are full of natural goodness, but a new inductively coupled plasma atomic emission spectroscopy (ICP-OES) and cold vapour atomic absorption spectrometry (CV-AAS) study reveals that while at least one species may be rich in essential trace metals it can also contain toxic elements such as mercury.

All four corners: NMR and chiral carbons

A new approach to chiral synthesis that works under mild conditions has been validated with nuclear magnetic resonance (NMR) spectroscopy and other tools by scientists in Europe. Paolo Melchiorre of ICIQ, Institute Of Chemical Research Of Catalonia, and colleagues developed the technique using enantioselective iminium ion chemistry and photoredox catalysis to form quaternary carbon stereocentres with high enantioselectivity.

While even the best analytical techniques cannot rectify problems generated by sloppy sample preparation, this less "sexy" step between the point at which analytes are transferred from the sample matrix to a form suitable for analysis is often overlooked. Read a free chapter from "Sample Preparation Techniques in Analytical Chemistry " here.

In this tutorial Dr Gary M Hieftje from Indiana University takes us right back to the grass roots of atomic spectroscopy making it ideal reading for either the graduate or anyone wishing learn more about this important branch of analytical chemistry.

The infrared spectrum is rich in information, and this article by John Coates, taken from the highly acclaimed Encyclopedia of Analytical Chemistry is intended to help the reader to extract the maximum information.
