August 2016 Issue of The Analytical Scientist

Welcome to the August issue! Our Upfront section covers Zika sensors, NASA flying labs and Polynesian artifacts, as well as updates on the analytical science business world, and sharing what SciX speakers are looking forward to at this year’s conference. MA-XRF is the real star of the show, as art experts uncover the secrets beneath paintings by van Gogh and others. And whether measuring maple syrup, detecting galactic dark matter or sampling deep-sea sediment, our image feature shows the beauty that can be found in our analytical world.

Intrinsic viscosity measurements on sRAGE protein

| Sponsored by Malvern Panalytical

In this application note, intrinsic viscosity measurements were performed on the sRAGE protein to establish whether the detector was able to detect and characterize the conformational change induced by the presence of calcium. Light scattering molecular weight measurements were also performed. Data are also presented showing that the conformation of sRAGE changes in the presence and absence of calcium.

Detection and quantification of large protein aggregates

| Sponsored by Malvern Panalytical

The complementarities of two techniques, dynamic light scattering (DLS) and static light scattering detector coupled with a size exclusion chromatography system (SEC-LS), are illustrated by studying a number of samples where a thermally denatured and aggregated protein sample were dosed at different levels into a non-denatured protein sample.

Solvent Enhanced Light Scattering of Fluoro-Polyester

| Sponsored by Malvern Panalytical

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.

Case studies: Ink formulation's analytical strategies

| Sponsored by Malvern Panalytical

This white paper offers practical guidance on using a range of analytical techniques, including rheology, particle size and zeta potential measurement to assist in the formulation of Inkjet inks.

Characterizing method for polymers

| Sponsored by Malvern Panalytical

This whitepaper reviews the methods available for measuring the key characteristics of polymers focusing on the benefits and value of gel permeation / size exclusion chromatography (GPC/SEC). Much of the paper talks exclusively about polymers, however many of the principles discussed are equally applicable to proteins or protein conjugate materials.
