Working hard to achieve other people's goals - a sentiment that defines the analytical sciences.

Traditionally in GPC, the sample dissolution solvent and the mobile phase are one and the same. However, a closer look at the demands of sample solvent and mobile phase suggests that this should not always be the case.

A sneak preview of the 2016 SciX conference, taking place in Minneapolis in Spetember.

Products, partnerships, investments - what’s going on in the analytical science business world.

This article explores how multiple detectors, particularly light scattering detectors, may be used for size-exclusion chromatography (SEC) in protein analysis. Using a light scattering detector as part of a multi-detector Size Exclusion Chromatography system provides the accurate molecular weight (MW) data needed to assess the activity, safety and clinical efficacy of therapeutic proteins.

The newest addition to the popular ‘10 ways to…’ series of educational papers provides practical guidance on developing high performance suspension products with enhanced consumer appeal. ‘10 ways to...control rheology by changing particle properties’ explores how controlling particle characteristics, such as particle size distribution, concentration and zeta potential, enables formulators to engineer suspension performance. Suspensions are used in the formulation of a wide range of every day products from medicines, drinks and foodstuffs to paints, inks and coatings. This paper is therefore valuable to formulators working across a wide range of industries.

When it comes to microsampling for quantitative bioanalysis, the devil is certainly in the details. But we should learn from our mistakes – not retreat back into convention.

Detecting and controlling mutagenic impurities in pharmaceuticals is challenging. What is ICH M7 and what do you need in your analytical toolbox?

In this application note, a purified polyclonal antibody (IgG) is separated using Size Exclusion Chromatography (SEC) and characterized using the Viscotek SEC-MALS 20, allowing calculation of molecular weight and radius of gyration (Rg).
