Can I use DLS for xyz?

How can I use DLS for sample xyz? What is the best sample concentration / refractive index for reliable DLS size measurements? Has it been done before? In Dynamic Light Scattering (DLS) we analyze intensity fluctuations in the sample to…READ MORE >

Intensity-Volume-Number: Which size is correct?

Over the years one of the most frequently asked questions stands out in the data analysis of dynamic light scattering results. It is the issue about which size we should report when interpreting DLS results. For this intensity-volume-number conundrum, which…READ MORE >

Dishwashing with chamomile – DLS shows super micelles

Washing dishes with DLS   How does dish washing work? Surfactants have seemingly magical properties: combine greasy plates with dish washing liquid and hot water and the dishes become squeaky clean again. So, how does that actually work? Detergents are…READ MORE >

What is a narrow band filter?

For fluorescent samples (like quantum dots) the Zetasizer has an option that can minimize the effect of (incoherent and thus undesirable for dynamic light scattering) fluorescent light: the narrow band filter eliminates most light that is not very close to…READ MORE >

Zetasize at a university near you!

It’s not unusual to see a Malvern Zetasizer in a University laboratory. In fact, there are so many educational institutions taking advantage of the quick and reliable information dynamic light scattering (as well as electrophoretic light scattering) can provide, that…READ MORE >

How do DLS size results differ with angle?

You may have noticed that the Zetasizer instrument range is available in two different optical configurations: the ‘traditional’ 90 degree setup and the ‘NIBS’ 173 degree setup. An obvious question for a dynamic light scattering (DLS) user is: “Will I get the same results…READ MORE >
