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.
Nanoparticle Tracking Analysis at PTL
Nanoparticle Tracking Analysis (NTA), or particle tracking analysis (PTA), is a technique that sizes material in the sub-micron region. The basic components of the instrument that performs NTA are an injector, a fluid cell, a microscope set to
Deciphering USP <788>: Particulate Matter in Injections
Within the pharmaceutical, health care, and numerous other industries, ensuring a product meets the quality standards outlined by the FDA is paramount to ensuring safety and efficacy. In the case of injectable products, the United States Pharmacopeia (USP)
Laser Diffraction or Single Particle Optical Sensing: Which Is Right for You?
Laser diffraction and Single Particle Optical Sensing (SPOS) are some of the most commonly used techniques in the determination of particle size. PTL offers both of these services, but how do you know which technique better suits your
Sand: It’s Not Just for Beaches!
While the word “sand” may conjure up visions of shimmering beaches or children’s sandboxes, in everyday life, sand plays a critical role in many water filtration systems used for municipal water treatment and industrial wastewater effluent. Sand filters
What Does Particle Size Testing by “Best Method” Mean?
In the intricate world of materials science and engineering, the significance of particle size cannot be overstated. The dimensions of particles play a pivotal role in determining the physical, chemical, and mechanical properties of materials, influencing everything from
