Around the world in 80 particles – Part 2
When I was first offered my job as a product technical specialist at Malvern Panalytical (was Malvern Instruments at the time), I called my parents to tell them all about it. Because my mum is of the age where girls in the UK were taught domestic science in school rather than biology, chemistry and physics, she has a kind of ‘mental block’ about science. Anyway, she said, “But Sarennah, where are all these particles? What are they?” And that stumped me for a moment. Because I work with laser diffraction, which means I specialize in characterizing particle size, and so I know particles are everywhere, in almost every manufacturing process and product one can buy.
Particles around the world
This year there will be a theme of “Particles around the world” for a series of blog posts from our technical specialists. And it has fallen to me to write the introductory post. So, I thought of Phileas Fogg and I gave myself five minutes to come up with 80 different particles:
Abrasives for carpentry | Ink jet inks |
Abrasives for cleaning products | Innovator drugs |
Active pharmaceutical ingredient powders | Lactose |
Agrochemical sprays | Magnesium stearate |
Air fresheners | Matcha green tea |
Athletes foot powder | Metal flakes for paints |
Baby powder | Metal powders for additive manufacturing |
Bacteria | Meter-dosed inhaler formulations |
Binders | Mica flakes for iridescent eyeshadow |
Calcium carbonate | Nasal sprays |
Carbon nano-tubes | Nebuliser formulations |
Catalyst powders | Oil droplets in sea water near oil drilling platforms |
Cement | Oven cleaner |
Ceramic slurries applied by ink jet | Packaging materials |
Chocolate | Paper coatings |
Clay | Pest control |
Coal dust | Phages |
Coffee | Pigments for cosmetics |
Concrete | Pigments for paints |
Construction materials | Pollen |
Deodorant | Polymer feed stocks |
DNA | Preservatives |
Dried milk powder | Pigments for paints |
Drilling muds | Protein powders for athletes |
Dry powder inhaler formulations | Proteins |
E-cigarette vapor | Sand |
Excipients | Shell fragments |
Fertilizers | Silt |
Fire suppression systems | Smoke from scented candles |
Flour | Spray coatings |
Fortifying vitamins | Sugar |
Fuel injection sprays | Sweeteners |
Furniture polish | Tablet mixtures |
Generic drugs | Talc |
Graphene | Tea |
Graphite | Tobacco cigarette smoke |
Gravel | Vaccines |
Grit | Virus |
Hairspray | Water droplets in crude oil |
Industrial diamond | Window cleaner |
So, as you can see, particles really do surround us, and come in all sizes. Follow this blog series to learn more about particles characterized around the world using Mastersizer platforms.
