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

Meet London’s first ever flock of pollution-monitoring birds

For over 50 years, we have been continually striving to push the limits of quantitation for dioxins. But where do we stand today – and what’s our next plan of attack?

Drugs get a second chance to enter our bodies - via wastewater and fish…

Benthoctopus sp gets overly familiar with Alvin’s robotic manipulator arm at 2,300 meters down in the Gulf of Mexico.

Persistent organic pollutants (POPs) encompass a wide variety of contaminants, but they share one thing in common: they have the potential to hit headlines and cause huge disruption to the food and feed industry.
