An Introduction to Surface Area
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
Water Woes or Water Win? Probing Water Vapor Uptake and Release with Dynamic Vapor Sorption (DVS)
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
Demystifying Zeta Potential
Confused on what a zeta potential measurement is and when it’s useful? You are not alone. In this helpful Q and A, Laboratory Division Manager Ryan Keefer walks us through the basics of zeta potential, points out factors
Say Cheese … a Snapshot of Flowability in Cheese Powder!
Moisture Impact on Powders The physical properties of powders directly impact their processability. This probably isn’t a surprise to anyone, especially if you are previously aware of Particle Technology Labs and what we do for a living! Powder
What is the Difference Between Thermogravimetric Analysis (TGA) and Differential Scanning Calorimetry (DSC)
Spring is upon us, and with it comes fluctuating weather conditions! You’re enjoying some warmer days, but also a little worried how the extreme changes in temperature may affect your products. Thermal analysis can help you better understand
PTL Now Conducting Analyses for Hemp Derived CBD Oil and Emulsions Containing ≤0.3% THC
Particle Technology Labs is now conducting analyses for hemp derived CBD oil and emulsions containing ≤0.3% THC. Bioavailability, efficacy, and stability are just some characteristics of food and drug formulations that are attributed to specific particle size. At
PTL Installs New Humidity Chamber for Pre-analysis Conditioning
During the course of manufacturing, packaging, storage, or transportation, materials are often exposed to a variety of environmental factors, including differences in temperature and humidity. These changes can affect materials in ways which may impact the quality, reliability,
Dynamic Vapor Sorption System (DVS)
PTL’s newest instrument, the Surface Measurement Systems DVS Intrinsic is a highly sensitive, accurate means for determining the moisture sorption properties of a material. This can provide critical information on the stability, processing, performance, and storage of materials. The analysis is applicable to
Zeta Potential and Colloid Chemistry
ABSTRACT The US Food and Drug Administration often requests the measurement of zeta potential; however, there is virtually no guidance offered in any of the regulatory pharmacopoeias. Guidelines are available in other standards, and there exists a wealth
