When people are looking for a way to measure small amounts of moisture, we often recommend the Karl Fischer method.
What is Karl Fischer?

At first glance, viscosity seems like a fairly simple concept. It helps describe how thick a product is, or how well it flows. That's all, right?
In reality, there are several different terms that come under the heading of viscosity. These terms are derived from how the viscosity is measured. When people talk about viscosity, they are talking about one of two things: kinematic viscosity or dynamic viscosity.
It's not easy to find a lot of information on the differences between dynamic and kinematic viscosity. This is my attempt to bring clarity to these two principal concepts.

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. In this article, I will explain the difference between Karl Fischer Titration and Loss-on Drying, and offer some suggestions to help you choose the right method for your application.

We recently redesigned our E-commerce site. The redesign proceeded without a hitch, until we got to the sieves.

I had a long conversation with the person [we'll call him Bill] responsible for setting up the quality procedures for very tight specifications in a new process -- part of which was developing procedures for checking the ongoing tolerances of production sieves.

Welcome to my beginner's guide to Surface Tension, Surfactants, and Micelles. In this blog, we'll be exploring the basics of these topics in order to better understand their role in industry and everyday life. Surface tension is a crucial property of a liquid that allows it to resist being pulled apart by gravity, and surfactants are molecules that can lower the surface tension of water. Micelles are spherical structures that are formed when surfactants reach a certain concentration in water, and they play an important role in many cleaning and industrial processes. We'll be discussing all of this and more in this blog, so let's get started!

I keep running into this kind of thing.
There is a recurring question we are asked as instrument manufacturers:
"Is my equipment working OK?"
This is of particular concern when a production process seems to be off standard.
QC says: "Clearly Process Problems"
Production says: "Bad Test Results"
These challenges arise often.
What to do?
