The chemical analysis chain is only strong if the quality system takes into account each and every link – including those that can sometimes be neglected or forgotten.

Having attended Pat Sandra’s lecture at Riva 2014 and read The Analytical Scientist’s feature on sample preparation, I can certainly say that Pat has succeeded in igniting discussion on the topic. Here’s my silver Sickle’s worth.

Whey is a by-product of the cheese-making process, and Whey Protein Isolate (WPI) is a dietary supplement and food ingredient created by separating components from milk. It contains a high percentage of pure protein and can be pure enough to be virtually lactose free, carbohydrate free, fat free, and cholesterol free. In this application note, a sample of WPI was characterized using the Viscotek TDAmax. The 4 main components in this mixture were separated and individually characterized.
This application note presents an example of how calorimetry aided the formulation development for ProX by providing insight into excipient-protein interactions. Polysorbate-80 and phenol are examined here as potential additives to the formulation buffer for ProX.

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:
