In this blog post, we look at the history of the software ‘bug’ and explain how not everything that appears to be a software issue is caused by the software itself. With this in mind, we examine how the new design of the Morphologi 4 and Morphologi 4-ID  has helped reduce the risk of environmental issues causing problems which may previously have been mistaken for bugs in the software.  
The term ‘bug’ was used as far back as the 1870s to describe errors or glitches in a system. Early adopters of the …

[4 Oct 2018 | ]

The most common approach for measuring time-dependent viscoelastic properties of a material on a rotational rheometer is to perform small amplitude oscillatory shear (SAOS) over a range of oscillation frequencies – commonly referred to as a frequency sweep – where the sample is oscillated back and forth with a given stress or strain. Here the oscillation frequency, measured in rad/s, is equivalent to 1/t, with t the deformation time of the material.
Let’s consider a sample of Play Putty which is a viscoelastic material. At short deformation times (high frequencies) Play …

Debye Screening – what is it?
 
In colloidal samples (and this spans the whole range from molecules in solution to particles in a dispersion) the movement of and forces between objects are often governed by the charge affecting neighbors. When we measure zeta potential (by electrophoretic light scattering), the determination of the effective charge of particles is really what is probed. In other words: zeta potential (or electrophoretic mobility) is a measure of how the charge of a particle/molecule is influencing the movement of another particle/molecule. The full potential as a …

How can we obtain the applied field strength?
When performing electrophoretic light scattering (ELS) measurements, the sample is exposed to an externally applied electric field, and we observe the extra movement that the particles undergo as a result of the applied field with the changes in the phase difference between the un-scattered reference laser beam and the scattering from the particles. The electrophoretic mobility µ is the particle velocity v divided by the electric field strength E, where the field strength is the applied voltage over the distance between the electrodes [typically …

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 …

Have you ever tried to explain to someone that the large peak they can see in their dynamic light scattering data, that seems to dominate the size distribution by intensity – is actually only a very tiny part of the sample…and hardly ‘there’ at all?
This has happened to me on numerous occasions, and I always try to show the volume and number size distributions, illustrating how that peak disappears. However, there is often a lingering question hanging in the air: “But if we see it, then it’s there, right?”
In the …

Check your manufacturing waste before disposing
In the last two years, companies in Asia have been fined for disposing of used industrial waste tainted with chemicals and heavy metals into the waters. In Vietnam, fish carcasses washed up on the beaches of Hà Tĩnh, many fishermen lost their livelihoods and needless to mention about water safety. While these companies have received fines, it is fair to say that waste management affects the public and ecosystem.
Malvern Panalytical supports companies with analytical solutions which ensure socially responsible disposal of used industrial water. Here are …

[15 Mar 2018 | ]

Dynamic Light Scattering (DLS), sometimes referred to as Photon Correlation Spectroscopy or Quasi-Elastic Light Scattering, is a technique classically used for measuring the size of particles typically in the sub-micron region, dispersed in a liquid. The sensitivity of some modern systems is such that it can also now be used to measure the size of macromolecules in solution.
In this new webinar, I summarise how the technique works, what its size and concentration limits are and discuss its advantages and disadvantages.
This webinar was well-attended and I received several questions, I thought …

For quality and process control many elemental analysis techniques are available. Let’s see how ICP, AAS, ICP-MS, ICP-OES and X-ray fluorescence spectroscopy (XRF) stack up are traditional techniques used in many industries. Each of these techniques has a number of advantages and disadvantages giving the analyst the flexibility to choose which technology suits best. When the required limits of quantification are above 1 ppm (µg/g), or when the non-destructive analysis is required, XRF is a very attractive technique that should be considered, especially when analyzing solids, powders, slurries, filters, and …
