How Long Does a Water Activity Test Take?

Posted by Amanda Ranowsky on Jul 27, 2017 8:00:00 AM

The answer to the question, “How Long Does a Water Activity Test Take?” is, as with most testing questions, “it depends.” Some water activity meters promise a test completed in a very short time; some in as little as five minutes. This time is an arbitrary selection that may or may not produce a satisfactory result.

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.

How Wide Is The Moisture Measurement World?

Posted by Art Gatenby on May 13, 2014 6:26:00 PM

At one end of the spectrum of the moisture world is the classic Speedy Moisture Tester where you use the reaction of water with calcium carbide to cause a mini explosion resulting in a moisture measurement reading. This method is used frequently for soils, concrete, and other like materials.

Can You Do a Fast Moisture Test?

Posted by Art Gatenby on Jan 24, 2014 9:51:00 AM

Can you do a fast moisture test?  The answer is, “maybe”.

The direct methods of Loss on Drying and Karl Fischer have the benefit that between them they can get a good moisture content result on almost any product or material.

But these tests usually take several minutes.

When you need the moisture content in a truck load of grain while the load is being dumped, or when you need to check several hundred bags of coffee at an auction, or when you need to get a moisture gradient in a pile of corn, a faster test is crucial.

 

Can you do it?

 

The short answer is, “yes”.  There are, however certain caveats to this answer.

Karl Fischer vs. Loss-On Drying - Which Method is the Best?

Posted by Amanda Ranowsky on Nov 19, 2013 9:00:00 AM

Karl Fischer Titration and Loss on Drying (LOD) are both methods for determining moisture content in a product. 

That’s where the similarities end, though. Here’s the difference between Karl Fischer and Loss on Drying:

What Can I Use To Get The Moisture Content In My Product?

Posted by Art Gatenby on Oct 3, 2013 5:36:00 PM

A question we get a lot is:

“How do I determine the moisture in my product?

Of course, the answer is often “it depends”, and the method does depend on the chemical and physical composition of the product. There are several methods used to determine moisture content: Loss-on-Drying (also known as Weight Loss), Karl Fischer, NIR, and Radio Frequency.
