Mass Spectrometry

How to bring better diagnostic tests to the market to benefit patients.

In this application note, we'll describe the successful molecular weight measurement of a polystyrene, PMMA and PVC sample using the OMNISEC system. This instrument can accurately measure the absolute molecular weight of any polymers independent of elution volume or structure. Although the measurements here have been performed using simple polymers, these methods can be applied to any polymer measured by GPC.

How to compare and contrast biosensor performance

Particle agglomeration can compromise the clinical efficacy of pharmaceutical products and must therefore be closely controlled. Automated particle image analysis provides one technology which can aid agglomerate detection. This article provides practical guidance on how imaging can be applied as a routine method to robustly identify and quantify the state of agglomeration of pharmaceutical formulations.

My love of biology, mass spectrometry and computer programming has led me down an uncommonly rewarding path of discovery and innovation. Here, I share some of my story and look towards the horizon of my exciting and ever-changing field.

Sons and daughters; love and lemur scent

Conventional mass spectrometry can only measure the mass of a molecule – what if you could image the same molecule simultaneously?

Actually, I don’t have the power. But you do, as we launch the 2015 Power List to celebrate the Top 100 most influential analytical scientists.

As associate scientific director of Nutritional Chemistry and Food Safety at Covance Laboratories, Katerina Mastovska must tackle the most challenging analytical questions. And she loves every second.

As new technology platforms push us to the limits of what’s possible, the metabolomics community is closing in on the future of the field: routine and rapid quantitative analysis.
