How Do You Analyze Small, Micron-Sized Particles?

Posted by Art Gatenby on Jan 30, 2014 2:00:00 PM

Sieve testing, as I have stated many times, is the Cinderella of particle size analysis because it delivers more value than expected from something that’s so easy to use and relatively inexpensive. However, the problem with standard sieving techniques using wire mesh sieves is that they begin to exhibit accuracy problems in the lower micron sizes.

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.
