This article explains how an inline probe was used to monitor a granulation at three different scales to confirm that, in each case, the granules produced were the same size, and more importantly produced tablets of identical quality as quantified by hardness.

Quantifying Nanoparticle Concentration and Size to Optimize Filtration Processes

The core of Uranus could contain significant amounts of exotic chemical compounds

Nanoparticle Tracking Analysis (NTA) has found use in a variety of investigations researching the toxicity and environmental impact of nanoparticles. Here we discuss various publications in which NTA has been used to measure particle size and concentration of nanomaterials in waste water.

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.

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.

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.

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.

Using PTR-MS to track the chemistry of group emotion

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.
