Dynamic Light Scattering (DLS), Photon Correlation Spectroscopy (PCS), or Quasi-Elastic Light Scattering (QELS) – this technique goes by many names, but what does it measure, how is it measured, and what do the results mean? From John Tyndall’s
Have you noticed? Particle Technology Labs recently launched a new brand identity and website. If you are a PTL customer, you may have already seen our new logo on PTL reports. PTL website users will find the new
Enmeshed in the World – An Overview of Sieving Sieving is an analytical technique that has withstood the test of time due to its excellent ability to quickly provide the particle size distribution over a wide analytical range.
In 1992, Lisa Jandacek, a stay-at-home mom, decided to pick up a 10-hour-a-month contract work with a new sci-tech startup called Particle Technology Labs. She’d be in accounting. The founder and sole full-time employee, Richard F. Karuhn, would
Understanding the differences in density types is key to requesting the most appropriate analysis for your sample type and needs. This blog will explain some of the different density analyses for solids offered by PTL. All density types
Surface area is an important property of solids with many industrial applications. This article will cover what surface area is, what affects it, how it is determined and how does gas adsorption work in the laboratory on a
Single Particle Optical Sensing (SPOS) is widely used across a variety of industries due to its excellent resolution, wide dynamic range and high accuracy. The term SPOS and Light Obscuration (LO) are often used interchangeably in the particle
Laser diffraction is an excellent technique for determining particle size as it allows the user to measure particle size on both a liquid and dry basis. When working with dry materials choosing the most appropriate way to disperse
Water is one of the most important substances on earth, yet it can also be the source of some major headaches throughout the lifecycle of a product. Uptake of moisture from the environment could cause unwanted changes in
