This four-part series examines common issues and questions surrounding the principles, measurements and analysis of DLS data and discusses how to minimize the time required for and increase the accuracy of acquiring and interpreting DLS data during the biotherapeutic development process. In Part Three, we cover the basic types of DLS deconvolution algorithms used to extract the intensity weighted particle size distribution from the measured correlogram.

This four-part series examines common issues and questions surrounding the principles, measurements and analysis of DLS data and discusses how to minimize the time required for and increase the accuracy of acquiring and interpreting DLS data during the biotherapeutic development process. In Part Two, we cover the influence of concentration effects and particle interactions on DLS results and provide a roadmap for identifying and distinguishing each type of concentration effect.

This four-part series examines common issues and questions surrounding the principles, measurements and analysis of DLS data and discusses how to minimize the time required for and increase the accuracy of acquiring and interpreting DLS data during the biotherapeutic development process. In Part One, we provide an overview of the key principles of DLS: theory, correlation statistics, deconvolution algorithms, and the intensity to mass transform.

The ability to quickly and reproducibly measure coffee ground particle size and size distributions is important during grinding operations to ensure that the coffee quality is maintained and that the correct grade is produced. The Mastersizer 3000 and the Funnel Sample Feeder for the Aero S dry powder disperser provides this capability, offering a rapid alternative to traditional sieve analysis.

As fraudsters become increasingly knowledgeable and adept, authentication of food and beverages becomes more and more challenging. I was keen to see if GC-Orbitrap technology represented a new tool in the defense of food safety and quality – and Scotland’s centuries-old whisky industry.

The Pesticide Explorer Collection offers complete workflow-driven solutions to meet the challenges of modern pesticide residue analysis. Are you ready for a premium solution?

The analytical aspect of the food industry has changed significantly over the last decade – mainly because of advances in technology. From pesticide residues to metabolomic approaches, the field is now more exciting than ever.

Are we analyzing the right arsenic species or are organoarsenicals actually wolves in sheep’s clothing?

By Dietmar Knopp, Professor of Applied Biochemistry and Head of Group ‘Bioanalytics’ at the Chair of Analytical Chemistry, Institute of Hydrochemistry, Technische Universität München, Munich, Germany.

The control of microbes in food is a primary objective across the industry.
