Characterizing Phenolic Compounds in Fava Beans
Fava beans are a good source of polyphenols and are located in different parts of the plant. Phenolic compounds are thought to contribute to the overall antioxidant activities of plant foods. However, there is a lack of information on the phenolic composition of the seeds (beans) of some edible varieties. This has led a team of researchers based in Chile and Spain to use high performance liquid chromatography (HPLC) to identify the composition of a variety of immature fava seeds. More...

Analysis of Post-translational Modifications Using LC–MS-MS
Thursday, August 22, 2013
8:00 am PDT/11:00 am EDT/16:00BST/17:00 CEDT.
In this session, Dr Duncan Smith  and Dr John Griffiths (MS-Insight Ltd and Manchester University) explain the principles behind the analysis of a number of key post-translational modifications (PTMs) using LC-MS/MS techniques.
Recent Developments in Protein Glycosylation Analysis by HPLC with Charged Aerosol and Mass Spectrometric Detection
Tuesday, September 17, 2013
8:00 am PDT/ 11:00 am EDT/ 16:00 BST/ 17:00 CEDT.
This web seminar will discuss promising improvements to glycosylation analysis that couple unique HPLC stationary phases with direct measurement of glycans by charged aerosol detection and with flow-splitting for simultaneous mass spectrometry MS-MS detection. These strategies avoid problematic O-linked glycan degradation (“peeling”) associated with some other quantitative methods, and employs optimal conditions for heightened characterization using additional offline MS techniques for characterization.
Get More from Your Analytical Systems – Improve Utilization, Reduce Operating Costs and Focus Future Capital Purchases to improve Efficiency
Thursday, September 26, 2013
5:00 AM EDT ; 11:00 AM CET.
Every Laboratory must balance analytical system capacity, workload and throughput with operating and capital expense constraints. Often the information needed to drive spending decisions is subjective, limited or both. This Webinar will demonstrate how to objectively inform your decision-making around asset utilization, consumables usage, service event planning and capital expenditure, leading to increased efficiency in your laboratory.
