There is a wide range of commercially available particle characterization techniques that can be used to measure particulate samples. Each has its relative strengths and limitations and there is no universally applicable technique for all samples and all situations.
Which particle characterization techniques do I need?
A number of criteria must be considered when deciding which particle characterization techniques you need:
• which particle properties are important to me?
• what particle size range do I want to work over?
• are my samples polydisperse i.e. do I need a wide dynamic range?
• how quickly …

Greetings Malvern Blog subscribers, and welcome to May 2013. I want to start my second blog of the year off for you with a simple question.
When you look at the current array of Light Scattering based instruments for chromatographic detection of the molecular weight and structure of a protein do you cringe with fear? Is LALS better or worse than MALS? Should your system have one detection angle or 20? Do I want SLS, DLS, both, or simply neither!! Is triple detection better than just light scattering for proteins?
When it …

Hello every one, Debbie here- and just to update you all- I am now a Debbie Huck-Jones!
Well we are well into 2013 by now but if your new year resolution was to find out about new analytical techniques and you have not done anything about it yet, why not join me Tuesday 28th May for the first in our series of Imaging Masterclasses.
Maybe you are a laser diffraction user and would like to consider other options to complement that technique and  help you better understand your products.
You may have to …

For many particle characterization applications, a particle size distribution provides adequate information about the sample. However, for some applications particle shape can provide more appropriate or complementary information. There are three main categories where this is relevant:
Single particles or agglomerates?
Many particle sizing methods require complete dispersion of any agglomerates in the sample in order to make an appropriate measurement. Being able to view individual images in the dispersion and analyze them in terms of their outline shape allows the user to determine whether or not agglomerates are present and the …

Many customers are not as familiar with automated imaging as a particle characterization technique. Here are three good reasons why you might want to consider automated imaging in addition to your more established techniques such as laser diffraction or microscopy.
Better understanding of particle properties
Automated imaging can provide data on particle size, shape, transparency and chemical identity in one measurement. In contrast to ensemble-based techniques such as laser diffraction, each individual particle in the sample is measured one-by-one, providing high resolution detailed information. This is often used to complement data from …
