Invisible to the Eye, Critical to Compliance: Particle Testing in Eye Drops
When you tilt your head back and squeeze a drop of solution into your eye, you expect absolute purity. Because the eye is one of the most sensitive and vulnerable organs in the human body, even the slightest
What Is a Particle Size Distribution? And Why Does It Matter?
Particle size is one of the most critical material properties across industries. It influences how a drug is absorbed, how a pigment disperses, how an ore is processed, and how a powder flows through manufacturing equipment. The data
Particle Size and Concentration Testing for Data Center Cooling Systems
As data centers rapidly scale to support artificial intelligence (AI), cloud computing, and ever-increasing rack densities, the importance of liquid cooling grows. From direct-to-chip cold plates to immersion baths and traditional chilled-water loops, advanced cooling systems are now
The Ins and Outs of an Effective Filtration System
In filtration systems, the goal is simple: remove unwanted particles. But achieving that goal with precision depends on understanding the process at both ends—what’s going in, and what’s coming out. Particle Technology Labs works with customers to evaluate
What Particle Sizing Techniques Don’t Tell You
Digital microscopy provides a direct, visual approach to understanding particle morphology, making it an essential tool to complement many physical particle characterization analyses. It can reveal more information regarding a material’s particle shape, structure, and degree of dispersion
The Importance of Linearity in Dynamic Light Scattering
From skim milk to cosmetic products to semiconductors, the importance of understanding and characterizing nanometer-sized materials and their applications has never been more necessary. Among the various techniques and applications used to characterize materials on the nanometer scale,
Going, Going, Gone… Or Not?
When you send material to PTL for analysis, do you need your samples back? Perhaps they are difficult to produce, expensive, or highly proprietary. While we are always happy to send back any untested samples, we can’t always
An Oldie but a Goodie – The Importance of Sieves in the Modern Particle Characterization Lab
As the saying goes, “Times change, but things stay the same.” While this may seem contradictory in many aspects of science and the modern analytical lab due to advancements in technology and automation, there is still a place
What is Dispersion and Why Is It Important?
Particle characterization—the determination of a material’s physical and chemical properties—is a cornerstone of industries such as pharmaceuticals, materials science, biology, and environmental science. Among these properties, particle size is particularly crucial, influencing a material’s performance, stability, and application.
