Particle size

Particle size distributions from sub-nanometer to millimeters.

By far the most important physical property of particulate samples is particle size. Measurement of particle size distributions is routinely carried out across a wide range of industries and is often a critical parameter in the manufacture of many products.

Launching the latest Zetasizer in Mexico!
 
June was a special month at our Mexico City office. We held a specific launch party organized for the latest addition to our Zetasizer family of instruments – the Zetasizer Pro and the Zetasizer Ultra. One of the groundbreaking novelties in the new system is adaptive correlation, a new method to perform dynamic light scattering (DLS) measurements, where rapid correlation functions are classified as being steady state or transient. Steady-state data sets describe particles that are consistently part of the measurement volume and hence characteristic of …

What causes the most headaches for a particle characterization scientist?
There are many answers to this question, but one of the most obvious is dust or contaminants! As someone who regularly uses Dynamic Light Scattering (DLS) to measure particle size, the possibility of there being dust or contaminants in my sample is one of the things I always bear in mind.
The way I prepare my sample, the way I store my sample before measurement, remembering to put the measurement cap on the cuvette, but only after I’ve cleaned it using an …

Here at Malvern Panalytical, we seem to enjoy testing the rheological properties of drinks, particularly those of the alcoholic variety! John Duffy and Steve Carrington looked into the differences between traditional ales and they explored the properties of Guinness. Any excuse to go down the pub…!
Therefore, it was probably about time to explore the healthier option on the drinks menu, and an ideal hangover cure – smoothies. Additionally, this was a perfect opportunity to demonstrate our latest dispersion geometry using John’s loyal drinking partner – the Kinexus rheometer!
We decided to run …

I presented a new webinar focusing on “A basic introduction to Electrophoretic Light Scattering (ELS)“. In this presentation, I explained the importance of Zeta potential measurements for colloidal dispersions and how it is determined using ELS.
As you certainly know, Electrophoretic Light Scattering (ELS) is a technique used to measure the electrophoretic mobility of particles or molecules in solution. This measurement is used to determine Zeta potential, which is a measure of the electrostatic or charges repulsion/attraction between particles and is a predictor of emulsion and dispersion stability. Zeta potential is …

How good can a gold standard be?
 
When performing dynamic light scattering (DLS) measurements, we sometimes encounter especially nice data. An interesting issue to consider is the level of data quality one can expect to achieve, under ideal circumstances, when all other interferences are minimized. This is especially relevant at the smaller nanoscale where fewer standards are available, and to those who have less practical experience with sizing colloidal nanoparticles by DLS. How monodisperse can a good sample be? What are achievable polydispersity index (PDI) values to aspire to?
What is the …

Where is the Zetasizer used?
 
For around two decades, the Zetasizer range has been the de facto standard for performing dynamic light scattering (DLS) measurements on a wide range of particles and materials.
Today’s launch of the Zetasizer Pro and Zetasizer Ultra – which took place earlier today on May 23rd, 2018 – provides a good reason to summarize the key application areas for light scattering technology: both dynamic and electrophoretic! Where are these Zetasizers used? Where can we find them, in the real world?
Below is a list of key application focus areas:

The peaks in your distribution are out of order?
We recently received an email about the order of peaks in the Zetasizer software:
For data evaluation, is it possible to rearrange the NNLS results by order of particle size populations?”
How the peaks are shown (by area)

Size measurement results are typically viewed in the Intensity PSD (M) tab. This is part of the standard Size and Summary workspaces.  When a record contains more than one peak, these results will be tabulated in the table above the intensity size distribution. The default ordering in …

After a break of 4 years, it was great to get back to the Drug Delivery to the Lungs conference (DDL2017) in Edinburgh this year. After the snow and gales of previous years when I have visited it was rather quiet in terms of weather this year, but not in terms of content as this was varied and interesting. I caught up on some of the latest advances in inhaled device development targeting special populations, such as small children or critically ill patients. It was really exciting to see the …

Measuring aggregation temperature using the Zetasizer

In dynamic light scattering (DLS), the hydrodynamic size and size distribution of particles in solution can be obtained.  It may be of interest to examine this measurement as a function of time and temperature, or as a ‘trend’, as it is called in the Malvern Zetasizer software.  For biological protein samples, this temperature trend is particularly interesting: although at low temperatures a protein may be stable and show repeatable size (and scattering intensity) measurements, typically at some elevated temperature (Tagg), protein molecules will show a tendency …

Downstream in-line monitoring for better processes and products
Every second is critical towards rectifying a plant upset or ensuring efficient plant management. What if you could incorporate in-line analysis for your dry and liquid products?
Companies that introduced in-line particle size analysis at the milling stage noticed significantly less over-milling. Hence seeing as much as a 2% increase in plant throughput. In-line elemental analysis allows petrochemical companies to closely monitor Fe, Ni, V which destroy expensive catalysts.
Why incorporate in-line analysis?

The heavy cost of mining and minerals manufacturing
The importance of minerals as a production resource applies to many facets of our daily lives. For instance, the quality of concrete determines the smoothness of a road surface and the sturdiness of a building. However, with the ever-growing demands for quality cement, many have spurred manufacturing processes leading to hefty costs. Such costs incurred comes from wastage when having to reproduce cement because it does not meet the quality standard.
Based on a mechanical and civil engineering study, 6-15% of construction costs …
