Are we analyzing the right arsenic species or are organoarsenicals actually wolves in sheep’s clothing?

By Dietmar Knopp, Professor of Applied Biochemistry and Head of Group ‘Bioanalytics’ at the Chair of Analytical Chemistry, Institute of Hydrochemistry, Technische Universität München, Munich, Germany.

Genomics often steals the headlines, but could metabolomics be the true deliverer of personalized medicine?

Non-targeted profiling is progressing in many application areas, including food, drugs, environmental, proteomics and metabolomics – but how can we measure the suitability of our own methods?

Despite the recent bad press, cutting-edge analytical techniques are transforming the field of hair analysis

Laser ablation and ICP-MS has the answer

Predictive biomarkers in saliva may yield a simple, noninvasive diagnostic test

In this application note, we show that Malvern’s OmniSEC software can now communicate with Waters Empower® for the seamless exchange of sample sequences. This allows OmniSEC to follow the injections performed by a Waters SEC system and to synchronize data collection. A selection of proteins was used to demonstrate the measurement of protein molecular weight, oligomeric and aggregation state.

Four different polymers are analyzed by GPC/SEC to investigate the effect of molecular weight, dispersity and molecular structure on the final properties of the polymer.

Driving the quality and scope of pesticide residue analysis forward is a constant and global endeavor. Is it time to embrace full scan, high resolution and accurate mass?
