Accurate QC with Sieve Testing - Hiram’s Story Chapter III

Posted by Art Gatenby on Apr 9, 2013 3:25:00 PM

As you may remember Hiram is the Quality Control supervisor of a  specialty pellet manufacturer. His problem is to find a way to get his sieve-testing results done with two shifts and a limited budget.

Do I Need A Karl Fischer Oven?

Posted by Art Gatenby on Jan 23, 2013 6:20:00 PM

As you know the Karl Fischer Method of moisture analysis has a reputation of being water specific. The method works through the use of a special Karl Fischer Reagent.

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.

Coulometric Or Volumetric Karl Fischer -- Which Should I Use?

Posted by Art Gatenby on Jul 3, 2012 12:27:00 PM

As usual when we pose a question,like:

Should you use Coulometric or Volumetric Karl Fischer to measure moisture in your product?

We often get a the reaction, “So Who Cares?” We'll try to answer both questions.

Is Sieve Calibration Really The Holy Grail? Episode IV

Posted by Art Gatenby on Jun 18, 2012 4:01:00 PM

You may remember Pequeño and his family of very small 150 micron (150µ) particles being very determined to defeat sieve certification.
