Developing an effective strategy to combat food fraud can be challenging; it means thinking on your feet and staying ahead of the game.

How will modern genomics tools and other analytical breakthroughs drive forensic science?

The pursuit of the metabolome may no longer be a novel field, but it remains the biggest analytical challenge.

Why old technology or ideas still have a part to play when it comes to advancing analytical techniques.

What is the chemical nature of thought? What is memory? Why, over 2000 years since Aristotle first asked such questions, are we still searching?

Is pesticide residue analysis still a hot topic? Ahead of EPRW 2016 in Cyprus, current Chair – Despo Louca Christodoulou – and scientific organizing committee members Magnus Jezussek and Sonja Masselter discuss the importance of the field in challenging times.

... or sonicate until the cockroaches disappear. When writing is central to the job of assuring health, safety, and quality, can you afford to be loose with language prone to misunderstanding? Why take a chance? Here are a few strategies to edit your written work for quality control.

Sitting Down With... Frank Bright, Henry M. Woodburn Chair and SUNY Distinguished Professor, Department of Chemistry, University at Buffalo, New York.

In many European countries, the limit of lactose in lactose-free labelled products has been lowered from 100 to 10 mg/100 g product in recent years (1).

Learn about how the latest chromatography, mass spectrometry and software are accelerating confident decision making at Alexion Pharmaceuticals, Inc.

Althea have chosen to adopt new chromatography systems, designed and built for biotherapeutic characterization.

In this application note, a selection of proteins are separated using Size Exclusion Chromatograpghy (SEC). The molecular weights of their oligomers and aggregates are measured by SEC-MALS and the results discussed.

A sample of PMMA was analysed by Size Exclusion Chromatography with Triple detection, before and after sterilization. Reduction in the molecular weight was shown to be firstly by cleaving the polymer at the branching points.

This application note describes the use of a Zetasizer Nano ZSP to characterize the charge state of spidroins in different formulations. The earliest stages of spidroin aggregation in different formulations are then assessed using low-temperature synamic light scattering (DLS) thermal trend experiments.
