This blog explores some common mistakes made in the application of de-ionization hardware. Although a properly engineered and installed de-ionization system will prevent these potential mistakes at the start, post-installation modifications by those less knowledgeable about de-ionizing technology don’t always respect good design practices. Temperature Limits – In general, de-ionization systems are not intended to …
Preceding blogs on metrology have introduced some basic concepts which can serve as food for thought. Today, I would like to give you a couple of examples of the practical application of the concepts discussed so far in industrial cleaning applications. Monitoring Contaminant Removal – Everyone wants to know how long it takes for a …
No matter what is being measured, it is critical that the measuring instrument chosen be capable of providing an accurate and repeatable measurement of whatever needs measuring. It sounds simple – – but isn’t. In general, the larger the scale the less accurate an instrument becomes. Let’s use weight as an example. Weighing devices come …
At first it may sound like a “no-brainer,” but deciding what to measure can be a challenge. The first part of that challenge is determining what measurements are required to establish that a particular criteria has been met. The next is to determine if the tools required to perform the required measurements are available and, …
Metrology, simply, is the science of measuring things. Metrology is used extensively in the world of industrial cleaning to both control and quantify cleaning processes. Finding the right equipment and procedures to produce accurate and meaningful results is often a challenge for those without extensive knowledge of the science. The upcoming blogs on metrology are …
I’ve been “playing” with ultrasonics for over two-thirds of my life now and am absolutely convinced that there is still more to know about the technology than anyone knows. The “fish tank” in the lab continues to reveal more questions than answers when it comes to this complex technology. The Ultrasonic Fish Tank in the Lab Still, …
It occurred to me several years ago that when we look at an ultrasonic cleaning tank, we are usually looking in from the top. I wondered how ultrasonics looked from a “fish eye” view which spawned (get it?) what is now called the ultrasonic fish tank in our Jamestown, NY laboratory. In upcoming blogs, I …
From time to time here on the blog I will try to include some applications notes targeting specific cleaning applications and giving you a taste of the successes and challenges faced in each. Although you may not have a need for the specific information presented, you may, as cleaning technologists, find it interesting what other …
The test laboratory is a special kind of place. The work conducted in the laboratory is experimental which usually indicates that we are trying things that have not been tried before to see what happens or doesn’t happen. Fortunately, at least in the cleaning laboratory, it is not likely that we will initiate an uncontrolled …
Before we get into quantifying the particles we have harvested in the last few blogs, I would like to take a minute or two to talk about the specifications that define and govern the evaluation process. In upcoming blogs we will talk about the quantification of particles in general terms. In real life, there is …
