Analysis of Mushroom Farming – Mushrooms meet Malvern
Malvern Instruments has made its name in particle sizing: the flagships Mastersizer and  Zetasizer have become the de facto global standard tools for particle sizing from nanometers to millimeters.  The breadth of applications for these technologies is simply astounding and we are constantly seeing new uses in diverse areas. As just one example, the video below shows use of a Mastersizer 2000 in a Lingzhi mushroom research facility, where state-of-the-art cultivation techniques are developed and improved.

The Lingzhi mushroom is also known as the reishi mushroom …

Component-specific Particle Size
Follow that particle!

I’ve always thought it would be great to be the innocent driver in a movie chase scene who has to respond to the hero’s demand to ‘Follow that car’ as they try to keep tabs on the villain. I always imaged that this would unlock the silent racing driver within me, giving me the excuse to forget about speed limits and drive at the limits of my car’s performance. I’d also get the chance to practice my handbrake turns!
Although I have never been engaged in a …

Particle size of coffee and Premium coffee!
How the particle size of coffee can affect the taste and strength of coffee
As a Malvern product manager, I am privileged to get the chance to travel to different locations around the world in order to meet Malvern’s users and engage with our sales teams. As a result, I get to stay in a lot of hotels.
Now, as with other travellers, I have developed my own list of requirements for assessing whether a given hotel is worth visiting again. I don’t know what you …

One of the questions I am regularly asked by my Mastersizer customers is how much sample do I need to measure?
I get the feeling people are hoping for a simple answer, such as 1g, 10ml etc. Unfortunately, the science of sampling is not so straightforward…
An expert in sampling, Francis F Pitard, says “a sample is equitable when it is reproducible and accurate enough to satisfy both the supplier and the customer”. I take this to mean the results need to be reproducible AND have RSDs for the percentiles that satisfy …

Regular readers of this blog will know that one of the most important pieces of advice we provide with respect to setting product specifications or developing new methods is that one number is never enough. For example, a single measurement is always perfect and tells you nothing about how a method is performing – it is only by making repeat measurements that the method’s performance can be ascertained. And when it comes to setting specifications, selecting a single number from a Malvern analysis report and using it as a quality …

My name is Thea Miksch and I recently visited Malvern Instruments for a six day work experience placement.  It was quite a big thing for me since I came from Germany to the UK for this placement. I was a little scared that I wouldn’t understand anything about the technology, but the Malvern employees were great at explaining it so even I got it!
One of the many things I learned is that there is science behind everything. I never thought of the particle size of chocolate or the viscosity of …

Batteries, and the chargers for them, are everywhere. They are available in a wide range of specifications using a variety of chemistries. The characteristics of the battery are determined by the particle size of the electrolyte powder, or slurry, and the surface roughness of the electrodes, which is determined by the particle size of its coating. By controlling the surface area, through particle size, a battery can be optimised for high capacity or high power.
The capacity of a battery is the amount of electrical charge it can deliver at the …

I was stuck in traffic on the M8 travelling between Edinburgh and Glasgow when a news item really pricked my ears up. Scientists from Edinburgh University’s school of GeoSciences have been investigating better ways of measuring the extent of ash clouds following volcanic eruptions, looking at particle size.Following the Eyjafjallajokull Icelandic volcano eruption in 2010, the ash cloud drifted across the major flight paths in the North Atlantic and over Northern Europe and as a result, planes were grounded and people stranded. At first the airlines said they wouldn’t fly …

In this series of blogs I, and some of my colleagues, would like to share some of our experience in particle sizing for industrial applications. I thought we’d do this by going through an A to Z of industrial applications and as Aardvarks are too big for our instruments, we’ll start with A for abrasives.
To be an abrasive, a material needs to be harder than the material that you want remove or polish (unless you have got a very, very long time to wait – think glacial!). The original scale …

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 …

Malvern Instruments is a massive fan of Pittcon, so it’s no big surprise that we’re back for more this year.  For me, Pittcon 2015 will be even better than usual, as I’m coming over to (hopefully) sunny New Orleans to attend in person!  Last year I enjoyed the exhibition from the safety of my laptop; as Malvern’s social media manager I spent a lot of time chatting to all you lovely people via Twitter, and updating all of our social profiles with goings on from the show.  I’m super excited that this …

I’m just back from DDL25, the Drug Delivery to the Lungs conference in Edinburgh. Unlike previous years the snow wasn’t here to stay and we were able to enjoy the conference without too many meteorological distractions.
It was the 25th DDL and retrospection was the order of the day, with the DDL Lecture given by Prof Peter Stewart (Monash University) reviewing the history of powders for inhalation from 1989 to today and offering predictions of developments in the next 25 years. In 1989, powder scientists were beginning to consider inhalation, and what …

Having just been down to New Orleans or Nawlins (check out Captain Beefheart and His Magic Band’s pronunciation on the classic track Click Clack – I bought the album long before most of the readers were born!) for an ASTM E56 Nanotechnology meeting, my thoughts naturally turned to my next visit when Pittcon 2015 will be there (March 8 – 12, 2015: Ernest N.

I’ll be manning the Malvern stand at DDL25 – the 25th Drug Delivery to the Lungs conference – which is taking place in Edinburgh next week, starting on 10th December.  I’m a technical specialist for diffraction products at Malvern, so I know the Mastersizer and Spraytec instruments inside out.  My challenge to you is to bring along your dodgy data for me to diagnose!
Got problems with your MDI? No, not your metered dose inhalers, your Method Development Investigations!  Need help with your API? I’m talking about Awkward Peak Investigations, not …

At the start of the project to develop the  Hydro SV – the new small volume wet sample dispersion unit for the Mastersizer 3000 laser diffraction particle size analyzer – our product manager, Paul Kippax, presented the market requirements to the team and commented that “we just need a simple stirred cuvette…”
A simple product – what could be easier than that? I’ve since heard the following quote: “Any intelligent fool can make things bigger, more complex…. it takes a touch of genius – and a lot of courage – to move …

At school, I never really got the hang of biology classes, and instead preferred topics like chemistry and physics. However, one experiment I do remember from my short engagement with things biological was observing amoeba. These creatures provided an excellent introduction in understanding the processes of cell division. They also helped me understand something about how an ecosystem works, with even something as a simple as a single-celled organism having an important part to play in the food chain.
Well, those days of amoeba watching came back to me recently, as …

Coffee and Cocoa Particle Size
Chocolate and coffee, what a great combination! But which do you prefer – milk chocolate and a regular cup of coffee or perhaps an espresso with a square of dark chocolate? Milk chocolate and dark chocolate have different compositions and would be expected to taste differently but why does an espresso taste different from a regular cup of coffee if they are made from the same beans? Are there any similarities between coffee flavor and chocolate flavor?
The taste of the coffee we drink depends very much on …

How exciting is this? It is such a fantastic experience to see first-hand our customer’s reaction to the Hydro Sight and Hydro SV , new accessories for the Mastersizer 3000 which we launched at Powtech yesterday. It was great being part of the customer evaluation of the early prototype version of the Hydro Sight but this is even better.
Coming here to Powtech for my first product launch was actually quite nerve racking, but once I got into the first demonstration and showed off how the Hydro Sight allows users to …
