Don’t Worry - Karl Fischer is Easy

Posted by Art Gatenby on Nov 16, 2015 5:25:25 PM

When we first started measuring moisture with Karl Fischer, I was instructed in the complex chemical reactions involved. I was also was told that the process was skittish.

Is Test Sieve Certification All You Need?

Posted by Art Gatenby on Oct 29, 2015 1:45:10 PM

For several years, people in the test sieving business have been grousing about the difficulty of making sure that a test sieve certification is what they need. Anyone who is working with close tolerances in the smaller particle sizes, like 300 microns and smaller, have serious issues in matching results from test sieve to test sieve.

LOD is Really Simple, or Moisture Analysis for the Newbie

Posted by Art Gatenby on Jun 12, 2015 4:51:00 PM

One quiet night, long ago I was musing over moisture analysis and how easy it is to do using Loss-on Drying (LOD). Little did I know what was in store.

Is In-Line Moisture Measurement For You?

Posted by Art Gatenby on Feb 27, 2015 9:59:54 PM

Five years ago, we published an article on in-line vs. off-line moisture measurement. At that time we debated whether these measurement systems should be called on-line or in-line. We chose to use the term "on-line". Since then, however, the world of the internet became known as "online". So, to avoid confusion, we changed our view and now refer to direct measurement as "in-line" moisture measurement.

What is the Difference Between Dynamic and Kinematic Viscosity?

Posted by Amanda Ranowsky on Jan 15, 2015 6:31:24 PM

I’m always trying to find a simple vision of the material testing world. When I was assigned to our new Viscosity product line, I thought I’d found it. Then I was introduced to the concepts of the dynamic and kinematic factors of viscosity.

This is my attempt to bring clarity to these two principal ways to measure viscosity.

What's So Special About Picking A Sieve Shaker?

Posted by Art Gatenby on Jan 6, 2015 9:15:00 PM

If you take Sieve Shakers for granted, you may be surprised to know that the selection of the right shaker can have a profound effect on your sieving results.

Viscosity, Consistency and Surface Tension - What Are These Things?

Posted by Art Gatenby on Aug 27, 2014 12:56:00 PM

Nearly every day we have a question about differences between Viscosity, Consistency and Surface Tension. There is usually a second part of the question;

When is a Sieve Not a Sieve?

Posted by Amanda Ranowsky on Jul 17, 2014 5:00:00 AM

In our business, we use the word “sieve” to describe a piece of equipment that separates desired elements from unwanted material using a woven wire screen or mesh net. To others, “sieve” can mean something very different.

Dance Bars, Music Technology, and...Surface Tension?

Posted by Amanda Ranowsky on Jul 8, 2014 12:39:00 PM

What do an Irish music technology developer, a British manufacturer of arcade and retro-style furniture, and a dance bar in San Francisco have in common? Given a million guesses, I’d never have thought of this:
