One of the ways to describe surface tension in fluids is: the property of a liquid’s surface that resists force. It serves as a barrier to foreign materials and holds the liquid together. This ever-present property is caused by unbalanced forces on surface molecules that pull toward the main part of the liquid.
CSC Scientific Blog
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.
Hiram is a Quality Control Supervisor of a plant manufacturing specialty pellets. This is about his struggle with particle-size sieve testing and results analysis.
We are back with Hiram, the QC Supervisor in a specialty pellet plant. We pick up the story after the QC department was hit hard by the flu season.
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.
I am regularly startled by little things that trigger new understanding about our slice of the instrument World. This time it is about surface tension.
I am very excited about a new update to the CSC Digital Moisture Balance. To give you a perspective of why I’m excited about this Moisture Content Analyzer update, I thought you my be interested in the story of the transition from a classic mechanical moisture analyzer to the current highly robust and durable electronic instrument of today.
The CSC Sieve Analyzer
The CSC Sieve Analyzer was designed to deliver a record of a sieve test results, eliminate operator error and significantly reduce the time to process and calculate these results.
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.
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.
