Were early land plants responsible for the rise in oxygen that shaped the world as we know it?

Quantifying Nanoparticle Concentration and Size to Optimize Filtration Processes

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.

From galactic dark matter detectors to seaside spectroscopy, analytical scientists know no bounds.

We speak with scientists using analytical techniques to solve some of the art world's mysteries

PTR-TOF-MS takes a trip on NASA Flying Lab to analyse South Korea’s atmosphere

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.

A journey into the study of organic aerosols and the analysis of atmospheric processes

This article explores the role of different components within drilling muds, including barite and calcium carbonate. The need to achieve optimum particle sizes is examined, the application of laser diffraction is considered within this context. Fast, efficient and having a wide measurement range, laser diffraction delivers accurate, precise and reproducible particle size information. Offering automated analysis, it is a preferred method for drilling mud particle sizing and the focus of ongoing API efforts to develop a standard in this area.

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
