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?

In 2011 "Powder-Bulk Solids" published an article comparing certification process veracity with a sieve calibration process using calibrated glass microspheres (or beads). The certification process merely indicates that a sieve mesh conforms to a standard that has a wide tolerance regarding mesh openings. It is performed on a small number of openings. On the other hand, calibration using the calibrated beads results in a number representing the mean opening -- a result generated by actually performing a test encompassing at least 80% of the mesh openings.
The problems outlined in the article are still dogging todays QC Managers

Definition of a Tough Consistency Instrument
Sometimes we encounter a product that is so simple and rugged that it would be tempting to deem it indestructible. Consider a stainless steel trough with a gate and etched numbers on the bottom. Seems simple and the stainless would make it tough, right? That is not the case, but it has survived nearly unchanged for more than 85 years.
