Sample Preparation

The Zetasizer NanoSampler is a sample delivery system that ensures highly precise and reproducible automated loading of samples into your Zetasizer Nano for particle size measurements. The NanoSampler adds automation and unattended operation in a versatile, compact package, maximising the productivity of your Zetasizer Nano.

This application note provides an example of how Archimedes can be used to detect and quantify the formation of protein sub-visible particles and the introduction of silicone oil droplets, in response to shear stress.

In this application note we will look at two examples where the retention volume of a sample could not be used to obtain an accurate measure of the sample MW. We will also describe the additional information that can be obtained using these advanced detectors. This work has been performed in conjunction with the Institut Pasteur, Paris, France

Polymers can be loosely grouped into two structural categories – linear and branched.

Light scattering detectors play an important role in gel permeation chromatography and size exclusion chromatography (GPC/SEC) analysis because of their ability to directly measure molecular weight distribution. Multi angle light scattering (MALS) detectors are often chosen, in some instances because they provide the most accurate data for the measurement of the radius of gyration (Rg), and in others because they have become an accepted industry standard. The launch of Malvern Instruments’ new Viscotek SEC-MALS 20 detector extends commercial choice in this area and draws the technology into the spotlight.

Deeper consideration of individual analytical unit processes offers a more systematic approach to method development, ensuring that we don’t forget the basics in an increasingly sophisticated world.
