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.

It must be nearly Christmas as we find ourselves back in the beautiful city of Edinburgh once again for this year’s Drug Delivery to the Lungs (DDL) Conference. I’m especially delighted to be here this year, as we have the new Morphologi 4-ID taking pride of place on Malvern Panalytical’s stand! I can’t quite believe it is almost a year since it launched back in February.

As I write, the Morphologi 4-ID is currently hard at work, analyzing a dry powder inhalation sample and enabling component-specific measurement of particle size for …

Are you pondering which laser diffraction particle size analyzer to use for your scientific research?
Many people consider the number of Google Scholar publication references as an indicator of acceptance of a particular scientific instrument’s technique, performance, and value. The higher the number of publications, the more credibility people tend to offer towards the choice of that instrument for their important research needs.
After doing a search on Google Scholar for references to the Mastersizer 3000 as well as the Mastersizer 2000, and then comparing versus several other models of laser diffraction …

“It’s impossible to know what happens in the fog of war” said a former US Secretary of State.  But the scientists at Sandia Labs in New Mexico are working to fix that, with the help of a Spraytec laser diffraction system.
The Spraytec is used to measure the droplet size of the airborne droplets, to verify the fog being created is an accurate replica of what is found in nature.  By creating fog droplets with a known droplet size, fog environments are created that accurately replicate those found in specific situations. …

Liposomes have been attractive delivery systems for decades due to their composition of natural biological lipids and structural resemblance to cell membranes suggesting metabolic compatibility, low toxicity, biocompatibility and lack of a strong immune response1.  They are comprised of spherical vesicles with an aqueous core enclosed by one or more phospholipid bilayers or lamellae and are frequently classified based on their size, polydispersity, and number of bilayers2. Control over these parameters has remained a challenge with most preparation methods and is further accentuated when moving from a laboratory to industrial …

On October 2, 2018, we held a seminar entitled “Overcoming Characterization Challenges in Drug Formulation” in the Boston area.  It was a great opportunity to meet with many pharmaceutical scientists in the area and learn about their challenges and concerns.  The presentations addressed a number of topics of interest, from stability of formulations, trace phase and impurity detection, deformulation, root cause analysis, to optimizing small molecule candidate screening.  There were great questions from the audience, so we rounded up several questions and answers here to share.
How does the Mastersizer 3000 see …

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 …
