Could bottlenose dolphin breath analysis help with conservation efforts?

Determination of the common anions, such as bromide, chloride, fluoride, nitrate, nitrite, phosphate, and sulfate, is often needed in water analytics.

Rheology is the science of material flow. It is also a science with a reputation for some fairly daunting mathematics. But look past these first principles and rheology has immediate relevance in formulation which is readily appreciated and easily exploited.

Over the past few months, we’ve been asking you to send in the photos and images that best reflect the important and intriguing work that you do.

New components and measurement techniques continue to be introduced for the Zetasizer Nano. New to the system are a Surface Zeta Potential accessory and a new diffusion barrier method for improved zeta potential measurements of protein samples. Why is the Malvern Zetasizer Nano so popular and found in a broad range of applied and fundamental scientifi c projects across all industries and fields? Because, it is simply the most dynamic and broad ranged instrument on the market for solving technical issues in today’s research environment and it continues to evolve with new capabilities. Here are 10 reasons why you should choose the Zetasizer Nano:

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.

Taking gas chromatography into the field has the potential to detect crop disease sooner

The Zetasizer µV (MicroV) is a dual purpose light scattering instrument designed specifically for the analysis of proteins. Firstly, it is a highly sensitive cuvette based dynamic light scattering instrument with the same great performance as the market leading Zetasizer Nano. Secondly, by simply changing the cell, it becomes an absolute molecular weight and size detector that can be added to any Size Exclusion Chromatography system (such as the Viscotek TDAmax).

The Zetasizer Nano is the world's most widely used light scattering system, for measuring size, zeta potential and molecular weight. Applications range from characterizing high concentration colloids and nanoparticles, through to measurement of proteins and macromolecules in their native state, requiring as little as 12 microlitres of sample. The Zetasizer Nano can be used for the comprehensive characterization of proteins, colloids and nanoparticles, and is simple to use, highly sensitive, versatile and fast! This videos shows how quickly and easily a measurement can be made on the Zetasizer Nano.

In August, The Analytical Scientist will publish a special issue celebrating the very best images in the field of analytical science. And you have the chance to submit an image that defines your work.
