Moisture Content and Water Activity - What Are They?

Posted by Art Gatenby on May 30, 2013 1:23:00 PM

Many accessing our web site ask questions such as:

  • “How does water content affect water activity?”

  • "How is water activity different from water content?”

  • ”Can I convert from moisture to water activity?”

I previously commented on water activity and now hope to clarify the differences between water activity and moisture content. Given that both of these measurements deal with water connected to a material, we must first understand of water content in a product.

Advances In Sieves: Sieves Able to Strip Molecules From Fluids

Posted by Art Gatenby on Nov 19, 2012 2:32:00 PM

Sieves make understanding the world around us not just possible, but also easier.

And with the advancement of sieves, not only are we able to separate dry particle, but also sift molecules from fluid as well. With molecular sieves developed by MIT, we can now strip a molecule’s individual parts gives us a better understanding of how things come together and work, such as diseases or even DNA.

Sieve Calibration Is the Holy Grail !

Posted by Art Gatenby on Sep 11, 2012 1:11:00 PM

Yes Harry, there is a Santa Clause. Or, more specifically, there really is a Holy Grail for ensuring consistent particle size analysis. 

If you’ve been following along, you know it was proven by Pequeño and his family of 150 micron particles who tried to bust our friend Harry’s quality control by attempting to slip through the mesh in Harry’s test sieves and defeat sieve certification.

(If you missed this drama, check out previous posts in the Holy Grail series.)

Now that we have indeed confirmed that, yes, sieve calibration really is the Holy Grail that sieve testers have been looking for, let’s get to work and dive a little deeper. Let’s examine some methods of sieve calibration.
