Identification of foreign particulate matter using the Morphologi G3-ID

The Morphologi G3-ID enables simultaneous physical and chemical characterization of particle samples, enabling outlier particles to be identified as being part of a product formulation or genuine foreign particle contaminants.

Solvent Enhanced Light Scattering Technique Enhances Gel Permeation Chromatography Analysis

| Chris Mirley, Sean Daughtry, Wei Sen Wong

The ideal solvent for a material may not provide a sufficient refractive index difference for light scattering detection. This example of a biodegradable polymer shows how SELS is used to increase dn/dc to give enhanced detection sensitivity

Assessing the effect of formulation composition on spidroin charge and stability

| Sponsored by Malvern Panalytical

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.

Case study: Effects of gamma-ray sterilization on high molecular weight

| Baljit Ghatora

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.

Viscotek SEC-MALS 20 to measure protein aggregation

| Sponsored by Malvern Panalytical

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.

Bringing MOFs Down to Size

| James Strachan

MOFs can now be nano-fabricated - what impact could the materials have on analytical science?

Principles of Triple Detection GPC/SEC

| Sponsored by Malvern Panalytical

Triple detection GPC/SEC combines measurements from multiple detectors to offer not only increased amounts of data, but also increased amounts of information, which is made available by the combination of different detectors (and unobtainable using individual detectors separately). The theory of triple detection GPC/SEC is described here.
