Common Challenges During Method Validation
Method validation is a critical step toward routine analytical testing because it confirms that a testing method produces accurate, precise, and suitable results. Organizations across pharmaceutical, biotechnology, chemical, materials science, and manufacturing industries rely on validated methods to
How Porosity Impacts Material Performance and Quality
Porosity plays an immeasurable role in determining how materials behave, perform, and endure under real-world conditions. Whether a product serves the pharmaceutical, industrial, cosmetic, chemical, or advanced materials sector, the presence and distribution of pores can significantly influence
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
PTL Continues Three-Decade Streak of Observation-Free FDA Inspections
Particle Technology Labs (PTL) announces the successful completion of its most recent U.S. Food and Drug Administration (FDA) general compliance inspection, continuing the laboratory’s long-standing record of regulatory excellence. The multi-day inspection included a comprehensive review of PTL’s
The Physics Behind Laser Diffraction
Laser diffraction is one of the most popular particle sizing techniques for a variety of industries. Though the generation of data seems easy enough, how does laser diffraction actually work? The physics behind laser diffraction centers around light’s
From Lab Tech to Chemist III: Justin Williams Builds Expertise to Include Over 30 Analytical Techniques
In the world of material science, a single metallic burr on a washer or a microscopic particle in a saline drip can be the difference between a high-performing product and a catastrophic failure. Particle Technology Labs (PTL), chemists
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
