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, dynamic light scattering, nanoparticle tracking analysis, and zeta potential are characterization techniques being used to determine particle size and stability in CBD products, specifically those in the nanoparticle range.

Dynamic Light Scattering

Dynamic Light Scattering (DLS) is a commonly used term to describe a technique which measures the particle size and estimated distribution of submicron particulate systems. In addition, the terms Photon Correlation Spectroscopy (PCS) and Quasi-Elastic Light Scattering (QELS) have also been used historically to refer to the same analytical principle. By any name, the technique is widely recognized throughout the pharmaceutical and industrial world reflected in the existence of several...

Nanoparticle Tracking Analysis

Nanoparticle Tracking Analysis (NTA) technology is one of the first commercially available technologies allowing high-resolution particle size distribution on a number-weighted basis and concentration analyses of submicron particles.

Zeta Potential Analysis

Zeta Potential is the characterization of the electrokinetic potential of liquid-liquid or solid-liquid colloidal dispersions. Under the influence of an electric field, charged particles will exhibit certain electrokinetic effects including electrophoresis, electroosmosis, streaming potential, or sedimentation potential.2 At PTL, zeta potential is measured using either a Zetasizer Nano ZS (Malvern Panalytical) system or Litesizer 500 (Anton Paar) system. Both calculate zeta potential using the principle of electrophoresis.
