ISO16332 – Oil / Water separators
A while ago, I wrote a blog “Characterizing filter efficiency in diesel engines – ISO16332” about a cell we were designing to meet the challenges of new filters in filter efficiency testing. This has now been successfully launched and has quite a few installs at different customer sites.
The key features were a straight pass through system (no bends which could cause shearing) and a unique design which couples a narrow path length with optimization of the flow within the cell to meet the high concentrations …

Last week my kids got very frustrated with warm French toast and a new brand of chocolate spread. The French toast, was …of course…warm, and the chocolate was misbehaving: melting and dripping on their fingers …
Now, French toast (and chocolate spread) is a staple at our house but somehow this never happened before. Mom learned the lesson fast: for this new chocolate spread let the French toast cool first! But the little neurons started firing (wonder… I know, but it happens sometimes)…
Little questions and answers in my head: why now? – …

A large amount of testing is being performed globally to optimise the efficiency of oil / water separators in diesel engines.
The filters remove any solid components (rust, paint chips) that may cause wear on the engine as well as undissolved water (that will be present in the diesel).
Large water droplets are reasonably easy to remove, but increasingly the water droplets are present in the form of a fine emulsion. The recent addition of various fuel additives (especially in low sulphur diesels) act as surfactants and have the unwanted side effect …

As a confirmed space-geek ever since Halley’s Comet in 1986, lasers, or perhaps I should say laser guns in their various forms, have always been a part of my life. I’m not sure if I first met lasers in Star Wars or being fired at Doctor Who by a Dalek. But I do know they made a big impression on me. The lasers of sci-fi are flashy affairs, complete with awesome graphics, sound effects and implausible physics. Perhaps the most iconic being the lightsaber of Luke Skywalker. So I was …

Greater productivity with lower emissions.  These are the demands facing modern cement manufacturers. But when increasing production requires more energy, and the reactions that produce fresh cement manufacture directly release CO2, meeting emission targets can be tough. The solution may well lie with a combination of state-of-the-art automated manufacture and ancient technology…
2000 years ago volcanic ash was a key ingredient of Roman pozzolan cements.  And considering pozzolan cement has kept both the Pantheon and the Colosseum standing since then, few can question the fortitude of their engineering! Today many …

In January, we hosted a webinar, with not one, but two Malvern experts who talked about ‘Optimization and characterization of nanomaterials for drug delivery applications’ in relation to Liposomes.

The webinar focused on two complementary techniques that can help liposome characterization.  If you missed the webinar, you can view a recording on our website which includes really cool videos of nanoparticle tracking analysis in action.
Following the webinar, there were more questions than we could answer in the available time, so I asked Mike Kaszuba, our Zetasizer expert, and Pauline Carnell, our …

Particle Characterization Explained
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?
• …

Energy savings in cement production

Switching from manual operation to fully automated real-time monitoring and advanced process control
Few years ago Vulcan Materials Company upgraded its cement finishing circuit by installing an Advanced Process Control (APC) solution from Pavilion Technologies, a Rockwell Automation company, and real-time particle size analysis from Malvern Instruments. Together these solutions have transformed operation, highlighting more productive control strategies and delivering major gains, including:

A 15% improvement in one-day strength (although the plant is now targeting a 10% lower Blaine)

A 20% reduction in specific energy consumption, the amount of energy used to mill …

Considerations for steering particle size

Through this blog you will find postings that talk about how particle size influences product quality: the bioavailability of a drug; the stability of a paint; and the mouth feel of chocolate; for example. Many manufacturing sectors monitor and control particle size to reach product quality goals, and focusing on product performance is clearly critical.
Reading through a recent article though,  ‘Considerations for Steering Particle Size’, by Roger A. Barnum and James K. Prescott of Jenike & Johanson, Inc, I was reminded of a closely related but somewhat separate reason for …

Talking on-line analysis

As Materials Talks continues to grow, more of us at Malvern have the opportunity to welcome you into our discussions. I’m Rob Norris, Business Manager for Malvern’s Process Systems, so I’m particularly interested in any processing experience that you would like to share. My team applies Malvern’s analytical expertise in the form of rugged systems that measure in real time, within the industrial environment.
Why go on-line?
Across all manufacturing sectors there is a significant increase in the need for process analytical systems, and this requires technologies to move from lab to line. …

Sapphire optics & Windows

Sapphires full of promise
Public anticipation of Friday’s Royal festivities in the UK began with the announcement of Prince William’s engagement to Kate Middleton. The Prince demonstrated his intentions by presenting his future bride with a highly recognisable family heirloom; an 18-carat blue sapphire rimmed with diamonds, the same ring the Prince of Wales had presented to Lady Diana Spencer 30 years before.
Here at Malvern, we also woo with sapphires, promising them to every purchaser of an Insitec L or Parsum real-time particle size analyzer. With self-cleaning sapphire windows at the …

Introducing the Malvern portfolio

Because I’m now surrounded by rheologists, GPC experts, imaging specialists and process engineers, it’s easy for me to see how Malvern Instruments has evolved in the thirteen years since I joined. We still lead the world in the production of particle sizing system, however thanks to our activities over the last decade we’re now a more-complete materials characterization company with a range of complementary techniques which we can offer to enable customers to better understand their products.
Meet the techniques
If you only interface with one part of our company, though, you …
